REQUIRED TRAVEL DOCUMENTS

For U.S. citizens, passports are necessary for travel by land, sea, or air anywhere outside the United States. The only exception to the passport rule applies to "closed-loop" cruises (itineraries that begin and end at the same U.S. port).

A government-issued photo ID (such as a driver's license) and proof of citizenship (like a government-issued birth certificate) will suffice. Note that for kids younger than 16 years of age, a birth certificate (or its equivalent) alone will suffice. 

Your cruise boarding documents and personal identification are in hand. The required boarding documents can typically be printed out at home ahead of time; some lines will still send them out via old-fashioned snail mail, or the most popular way is to download the cruise line app. 

Passengers without acceptable identification will not be allowed on board and will not receive a refund if they miss the cruise for lack of correct documentation.
