For many travelers, a Caribbean vacation means visiting renowned spots like Jamaica or The Bahamas. While these destinations offer beautiful beaches and rich cultures, there are some lesser-known Caribbean islands that can further broaden your experience, whether you’re looking for untouched beaches or incredible historical sites. Now, with more than 7,000 islands in the Caribbean—dozens of which you can visit on a Royal Caribbean cruise, where should you start?

The muster (or safety) drill—a mandatory practice at the beginning of each cruise designed to show guests where they should go in the unlikely event of an emergency, how to put on a life jacket and other safety measures. It’s incredibly important, but it’s also the least favorite part of the cruise for guests since it requires pausing your vacation just when it’s getting started.
