Will I need a passport for this cruise?

The U.S. Department of State has information I'd feel comfortable relying on. In regards to Barbados they state: "Generally, all U.S. citizens are required to present a valid U.S. passport when traveling to Barbados, as well as proof of anticipated departure from Barbados. This includes travelers arriving by airplane and by private sea-going vessel. Those traveling to Barbados on a cruise may use another Western Hemisphere Travel Initiative (WHTI) compliant document. However, we strongly recommend visitors obtain a passport before travel in case of an unforeseen emergency that requires a cruise passenger to disembark and return by air." (emphasis added)

WHTI compliance documents include a birth certificate and government-issued photo ID.
