Carnival Mardi Gras Cruises 2025 Reviews. When carnival launched their first ship, 1972’s tss mardi gras, they made cruising a lot less stuffy, a bit less fancy, the kind of fun everybody could enjoy. The carnival mardi gras sails on july 19, 2025 for a 7 night eastern caribbean (port canaveral roundtrip).

How did this ship compare to the others and more importantly, would we book with carnival again? After 15 cruises on 6 other cruise lines, we took our first carnival cruise on the brand new mardi gras.
