Carnival vs Norwegian: the rules that actually differ

Carnival organizes the evening into two codes and tells you when each applies. Cruise Casual governs most nights in the main dining rooms and is more relaxed than people expect: for men and boys it lists sports slacks, trousers, khakis, jeans, tailored dress shorts and collared dress shirts or button downs, polo shirts or nice t-shirts, and for women and girls casual dresses or skirts, pants, capris, jeans, blouses and button down or pullover shirts. Tailored dress shorts sitting inside the main dining room code is worth noticing, because it is not true of every line. Cruise Elegant, which Carnival subtitles Sharp and Chic, is the dressy version: dress jeans, trousers, slacks, dress shirts and optional sport coats, with some men choosing a suit and tie or tuxedo, and dressy resort wear, party or cocktail dresses, pantsuits, elegant skirts and blouses, with some women in evening gowns. The count is published and so, roughly, is the timing. Select cruises of 5 days or shorter have one Cruise Elegant evening, cruises of 6 days or longer have two, and on longer sailings the first falls on the second or third evening while the next lands two or three evenings before the end. Carnival also publishes the refusals, and applies them to both codes: no ripped or cut-off t-shirts, nothing sheer or see-through, no athletic clothing or gear, and no swimwear, with the Steakhouse and Rudi's Seagrill held to the main dining room standard. Norwegian does none of this. Its own guidance for restaurants describes a single standard rather than a level, asking that attire feels put-together and suited to the setting, with shirts and footwear required, graphics respectful, and styles that offer appropriate coverage for a dining environment. It illustrates that with what you will actually see aboard: shorts with a collared shirt, statement sandals, breezy linens, crisp denim, easy dresses and button-downs with personality, alongside guests who make an occasion of the specialty restaurants. Two consequences follow for your suitcase. On a week-long Carnival sailing you need two outfits you would wear somewhere smart, and you can guess which nights. On a week-long Norwegian sailing you need none, and the only reason to bring one is that dressing up is part of your holiday.

• Carnival: Cruise Casual on most nights, including tailored dress shorts and jeans in the main dining room.
• Carnival: Cruise Elegant once on select sailings of 5 days or shorter and twice on 6 days or longer, with the first on the second or third evening.
• Carnival refuses ripped or cut-off t-shirts, sheer clothing, athletic gear and swimwear at both evening codes.
• Norwegian publishes no formal night and no tiers, only that attire should feel put-together and suited to the setting.
• Norwegian's own examples of restaurant wear include shorts with a collared shirt, breezy linens and crisp denim.

Code names, attire lists, elegant-night counts and the dining room refusals come from Carnival's own What to Wear guidance; the restaurant standard and examples come from Norwegian's own what to pack page, both read on August 9, 2026.

If you are switching between these lines, this is the rule that will cost you something at the terminal. Carnival permits a small quantity of non-alcoholic beverages on embarkation day, and defines the quantity precisely: a maximum of 12 sealed, unopened cans or cartons of 12 ounces or 354 ml each or less, per person, carried in the guest's own carry-on luggage. It is per person rather than per stateroom, which is generous for a family, and it is fussy about the container, because water, sodas and other non-alcoholic drinks packaged in glass or plastic bottles are prohibited outright. Carnival pairs that with a cooler rule, banning large coolers because moving them through embarkation impedes boarding and screening, while permitting a personal cooler no larger than 12 by 12 by 12 inches for small quantities of drinks or medication. Norwegian permits none of it. Effective for sailings from July 15, 2016 onward, guests are prohibited from bringing any beverages at all, including liquor, beer and non-alcoholic drinks such as water, soda and juices, as carry-on or as checked luggage. The exception is narrow: purified or distilled water in factory-sealed containers for use with a medical device or for reconstituting infant formula, and Norwegian asks guests who need it to contact its access desk beforehand for pre-approval to show security at embarkation. The line also publishes what happens if you turn up with a case anyway, which is the sentence to remember: guests who bring beverages to embarkation will be directed to return the items to their vehicle, and if the guest does not have a vehicle on site, the items will be disposed of. The same applies in ports of call, where locally purchased beverages are disposed of before reboarding. Alcohol is where the two lines briefly converge on a number and then diverge on the mechanism. Carnival allows one 750 ml bottle of sealed wine or champagne per guest aged 21 or older, in carry-on, on embarkation day only, excludes fortified wines over 15 percent ABV even within that allowance, and charges a $15.00 USD corkage fee per bottle only if you drink it in the main dining room, a specialty restaurant or a bar. Norwegian allows sealed wine and champagne but screens and charges at the pier, $15.00 USD for a 750 ml bottle and $30.00 USD for a 1,500 ml magnum, with the fee waived for guests holding a beverage package, and refuses box wine. Both lines store alcohol bought in port or in the onboard shops and hand it back at the end of the cruise.

• Carnival: 12 sealed cans or cartons of 12 ounces or less per person, in carry-on, on embarkation day; no glass or plastic bottles.
• Carnival: personal coolers up to 12 by 12 by 12 inches permitted as carry-on; large coolers prohibited.
• Norwegian: no outside beverages of any kind since sailings of July 15, 2016, except sealed water for a medical device or infant formula with prior approval.
• Norwegian directs guests with drinks back to their vehicle, and disposes of the drinks if there is no vehicle on site.
• Wine: one 750 ml bottle per adult on Carnival with $15.00 corkage only if served in a venue; on Norwegian, corkage of $15.00 or $30.00 charged at embarkation and waived with a beverage package.

Carnival publishes one of the most detailed prohibited items lists in the business, and Norwegian's is shorter but bans several things Carnival happily carries, so reading only one of them is how people lose property. They agree on the important safety items. Both prohibit appliances containing a heating element, Carnival naming irons, clothes steamers, immersion heaters, heating blankets, water heaters, coffee machines, hot plates, toasters and humidifiers, and Norwegian banning items containing any kind of heating element with much the same examples. Both prohibit cannabis in every form, Carnival naming marijuana, cannabis and derivatives such as CBD, and Norwegian naming all products containing CBD, oils, candies and gummies, or any product containing THC, plus marijuana prescribed for medical purposes. Both ban hoverboards and self-balancing devices, candles and incense, and both ban lasers and laser pointers. Then they separate. Carnival permits power strips, multi-plug box outlets and adaptors and extension cords without surge protectors when used with proper caution, along with fans no larger than 12 inches in diameter, and returns anything judged hazardous on debarkation morning. Norwegian does not name power strips at all, permits only small electrical or battery-operated fans, and warns that even those are subject to confiscation for inspection and approval. Carnival bans boom boxes, radios and all types of speakers including Bluetooth, portable and wireless, along with hookahs, helium filled balloons, inflatable kiddie pools, curtains and hanging room dividers, kava, and any footwear with wheels; it also asks guests to use earphones for music or video in public spaces and bars handheld clack fans from the nightclub and indoor dance floors. Norwegian's distinctive entries run elsewhere: metal detectors, kayaks, canoes and rafts, bicycles, walkie-talkies, portable modems, ham radios and satellite phones, and paper door decorations, which it bans by name because they are flammable. Drones are the sharpest reversal. Carnival allows one aboard provided it is identified at the terminal during check-in and held in the custody of the Chief Security Officer, checked out and back in by the owner for port use only and never used at Carnival's private destinations. Norwegian bans any remotely controlled or autonomously flying device outright. Finally, the consequences differ in tone. Carnival says items deemed dangerous will be removed and disposed of with no compensation provided, though hazard-flagged electrical devices come back on debarkation morning. Norwegian says prohibited items will be confiscated and not transported aboard, and that when an item is determined to be illegal the appropriate authorities will be informed.

• Both ban heating elements including irons and steamers, and both ban CBD and cannabis in any form.
• Carnival permits non-surge power strips, adaptors and extension cords; Norwegian's list does not name them.
• Carnival bans all speakers including Bluetooth, plus hookahs, helium balloons, kava and wheeled footwear.
• Norwegian bans metal detectors, kayaks, bicycles, walkie-talkies, portable modems and paper door decorations.
• Carnival stores a declared drone with the Chief Security Officer for port use; Norwegian refuses to carry one at all.

Carnival front-loads embarkation day into online check-in, and the deadlines it publishes are unusually concrete. Every guest must complete online check-in no later than midnight Eastern time the day before sailing, and during that process you select an Arrival Appointment, which Carnival defines as the time everyone in your stateroom should be at the cruise port terminal, asking that you arrive promptly within it to reduce your wait in line. At check-in you present your boarding pass, photo ID and citizenship documents, and bookings made within 24 hours of sailing require secondary screening. Two clocks then run. All guests must be on board by the Final Boarding time printed on the boarding pass or they will not be permitted to sail. Separately, and earlier, checked baggage service is only available until 2 hours before the published departure time, after which you are responsible for carrying your own bags aboard. Carnival also describes the rhythm of the morning: guests scheduled to arrive before 1:30 PM usually hand bags to a porter and eat lunch on the Lido Deck before staterooms open, and lunch runs from boarding until the safety briefing begins. Norwegian frames the same day around eDocs. Embarkation time is when you should arrive at the terminal, and the line asks that you do not arrive any earlier than one hour before it because security regulations might prohibit early entrance. Departure time is when the ship sails, and Norwegian highly encourages boarding no later than two hours before it. Online check-in should be done at least 3 days ahead, and the line warns that otherwise guests may face an extended check-in procedure or may even be denied boarding; the pier arrival check-in time itself is reserved from 21 days out. On luggage the lines share a weight and little else. Carnival caps bag count by sailing length, one bag per person on cruises of 3 to 5 days and no more than two on cruises of 6 days or longer, sets a 50-pound limit on each checked and carry-on case, and adds dimensions: lying flat, bags must not exceed 16 inches high by 24 inches wide, with length not a factor. It asks that luggage be unlocked for screening and warns that oversized or locked bags may be delayed. Norwegian publishes two checked bags per guest at 50 pounds each and notes that luggage may take a few hours after embarkation to reach the stateroom, which is the practical case for a carry-on with medication, documents and a swimsuit on either ship.

• Carnival: complete online check-in by midnight Eastern the day before sailing and arrive within your Arrival Appointment, the time your whole stateroom should be at the terminal.
• Carnival: be aboard by the Final Boarding time on your pass, and note checked baggage service closes 2 hours before published departure.
• Norwegian: arrive at the eDocs embarkation time, no earlier than one hour before it, and board no later than two hours before departure.
• Carnival's bag limit is one per person on 3 to 5 day cruises and two on 6 days or longer, 50 pounds each, no more than 16 by 24 inches lying flat, unlocked.
• Norwegian allows two checked bags per guest at 50 pounds each and warns that delivery to the stateroom can take a few hours.

The safety requirement is identical in law and different in practice, and it shapes what your first afternoon feels like. Carnival handles it as a task you complete on arrival rather than an event that stops the ship. Its own app guidance tells guests to learn about onboard safety and to navigate to their assigned muster station to check in with a team member upon boarding, which means the muster station is a place you visit when it suits you during embarkation rather than a bell you answer at a fixed hour. Carnival's description of embarkation lunch fits around it: lunch is served on the Lido Deck from boarding until the commencement of the safety briefing, so the briefing is a scheduled moment on the day, but your individual check-in is not. Norwegian runs a conventional drill and publishes the numbers. Its Life Boat Drill exists so guests understand what they are supposed to do and where they are supposed to go in an emergency, and the line notes it is required by International Maritime Law and the United States Coast Guard. On timing, Norwegian says the drill usually takes place right before the vessel departs and typically lasts between 30 and 40 minutes. On attendance it is unambiguous: you still have to attend whether you are a first-time cruiser or have cruised the line before. Two smaller published details prevent needless worry. You are not required to wear a lifejacket while participating, though you will be shown how to put one on at your assembly station. And your assembly station, a specific location on the ship where guests muster on the advice of the vessel's command, is printed on your stateroom key and on the back of your stateroom door, so you can find it before anyone announces anything. The planning takeaway is not about which system is better but about what each does to your afternoon. On Carnival, walk to your muster station soon after you board, get checked in, and the rest of the day is yours until the briefing. On Norwegian, assume the half hour before sailaway belongs to the ship, and do not book a spa slot or a specialty lunch against it.

• Carnival: navigate to your assigned muster station and check in with a team member upon boarding.
• Carnival: lunch runs on the Lido Deck from boarding until the safety briefing begins.
• Norwegian: a drill that usually takes place right before departure and typically lasts 30 to 40 minutes.
• Norwegian requires attendance regardless of how many times you have sailed the line.
• Norwegian does not require you to wear a lifejacket during the drill, and prints your assembly station on your key and the back of your stateroom door.

It is worth naming the limits of a policy comparison, because plenty of pages built like this one quietly overreach. We have not eaten our way through both fleets, we have not sat in both theaters on the same itinerary, and we have no data at all on the questions people usually mean when they ask which line is better. Whether Carnival's comedy club beats Norwegian's production shows, whether one line's balcony cabin feels roomier, whether either line's service is warmer, whether the fare on your dates is good value: none of that can be read off a published policy, and none of it is something this site has evidence for. Those questions belong to people who sail both lines repeatedly and disagree about them in public, and the honest advice is to read a lot of them rather than one confident summary. What a rules comparison can do is remove the expensive surprises, and there are several here. Whether your case of soda comes aboard or goes back to the car. Whether a bottle of wine costs you fifteen dollars at the pier or nothing at all. Whether the power strip in your suitcase is ordinary or contraband. Whether the Bluetooth speaker you packed for the balcony ever reaches the balcony. Whether you need a jacket. Whether your first afternoon includes a half-hour drill or a two-minute check-in. All of those are knowable before you leave home, and all of them are published by the lines themselves. One caveat to close on. Every figure here was read on August 9, 2026, and both lines revise these documents without announcing it. Carnival's own dress code notes that ship-by-ship facilities vary, and Norwegian's beverage policy is itself the result of a rewrite. Before you pack anything you would hate to lose, open your line's own page and check it still says what we say it says.

• No claim is made here about food, entertainment, cabins, service or price on either line.
• Every rule is attributed to the line that published it, with nothing carried across between columns.
• Where a line's published list is silent on an item, the silence is reported rather than filled in.
• Both lines reserve discretion over items and enforcement, so a published rule is a floor rather than a promise.
• All figures were read on August 9, 2026 and should be reconfirmed on the line's own page before you travel.
