U.S. Citizens 

Proper travel documentation is required at embarkation and throughout the cruise. Even though a guest has completed registration using Online Check-in, it is still the responsibility of the guest to present the required travel documents at the time of embarkation. Any guest without proper documents will not be allowed to board the vessel and no refund of the cruise fare will be issued. Carnival assumes no responsibility for advising guests of proper travel documentation.

Except where it is a mandatory requirement, Carnival highly recommends that all guests travel with a passport book. The passport book must be valid for at least six months beyond the completion of travel. This will enhance the debarkation experience as delays may be expected upon return to the United States for those without one. Additionally, this will enable guests to fly from the United States to meet their ship at a foreign port should they miss their scheduled port of embarkation and allow guests who must disembark the ship before their cruise ends, due to an emergency, to fly back to the United States without significant delays and complications.
