Belize and Honduras, which are sometimes included on these itineraries, also waive their passport requirements for cruise ship passengers. You can also cruise to the Mexican Riviera—destinations such as Cabo San Lucas, Puerto Vallarta, and Mazatlán—without a passport.
Do you need a passport to cruise to Dominican Republic?
U.S. citizens traveling by sea must now have either a U.S. passport, passport card, or other WHTI- compliant document. Be aware that the “enhanced driver's licenses” or “enhanced ID cards” offered by many states are not accepted by Dominican authorities for ferry travel from Puerto Rico.
Can you use your birth certificate instead of a passport for a cruise?
We strongly recommend that all guests present a passport as their form of ID on boarding day. Technically, yes – U.S. citizens can present a state-certified birth certificate and government-issued photo ID to sail on most cruises departing from the U.S. But a passport is the more efficient, secure option.
