If your name has changed since your document was issued (e.g., marriage or divorce), it is required that you update the document with the new name or provide an official supporting document (e.g., a state, county or province issued marriage license, divorce decree or legal name change document) of the name change.

Whether you need a marriage certificate on a Royal Caribbean cruise depends on your documentation and name consistency. If you are a U.S. citizen traveling on a "closed-loop" cruise (starting and ending at the same U.S. port) using a birth certificate and government-issued photo ID instead of a passport, you must bring an original or certified copy of your marriage certificate if your current legal last name on your ID differs from the name on your birth certificate. This serves as a "bridging document" to prove the legal name change. However, if you are traveling with a valid passport that matches the name on your cruise reservation, a marriage certificate is generally not required for boarding. It is also important to note that if you are planning to actually get married on the ship, you will need to provide a marriage license and other legal documents to the cruise line's wedding coordinator at least 90 days in advance. To avoid any potential denial of boarding in 2026, it is always safest to carry a copy of your marriage certificate if any of your travel documents feature a maiden name.
