Sail for the
festival.

Anyone can book a week in the Caribbean. The trick is landing on the one day the island throws its own party — and being ashore when it actually happens. Every festival below shows its real hours against a typical port call, so you know before you book whether you need a late departure, an overnight, or just a normal Tuesday. And when the answer is “get there a day early,” you already have the one thing nobody else on the ship has.
