Carnival requires guests to provide proper travel documentation in order to travel. The passport requirement does NOT apply to U.S. citizens traveling to or returning directly from a U.S. territory. Non-U.S Citizens must contact the appropriate Consulates, U.S. Embassy and U.S. Immigration office to inquire about necessary travel documentation. Carnival assumes no responsibility for advising guests of Immigration requirements.
It is recommended that all guests travel with a valid passport during their cruise. This will enable guests to fly from the U.S. to meet their ship at the first port should they miss their scheduled embarkation and allow guests that must disembark the ship before their cruise ends due to an emergency to fly back to the U.S without significant delays and complications. It is also recommended that all guests travel with a passport valid for at least 6 months beyond completion of travel.
*If you need to obtain a passport quickly, Carnival recommends that you contact ZVS at http://www.zvs.com/carnival or by phone: 1-866-788-1100. Callers should mention that they are sailing on Carnival to receive discounted service fees.
