Before you book

Is the cabin upgrade worth your budget?

Enter two whole-party quotes and compare the difference alongside the rest of your trip. A larger cabin only helps if the arrangement works for your party.

Get the same-sailing comparison right

Match the ship, departure port, sailing date, nights and refund terms. Check taxes and gratuities on both quotes. A fare difference is shown even if other costs are incomplete; a comparable nightly premium needs matching known terms.

The calculator is free and uses USD. Cabin comparison currently covers selected categories on Utopia of the Seas and Carnival Mardi Gras. It does not fetch current fares or confirm availability.
