#1Disney Cruise Line
Disney's ships sail to 14 ports across the Caribbean, with stops in top spots like St. Kitts and Grenada. Families are fans of this line thanks to its onboard and onshore activities and excursions for younger children. Kids get a kick out of featured activities like treasure hunts with Disney characters and swimming with dolphins. Couples also enjoy Disney cruises for their affordability and secluded, adults-only areas found on every ship. Plus, most of Disney's Caribbean cruises stop at Castaway Cay (the cruise line's own private island in the Bahamas), so everyone can take advantage of less-congested beaches and prime snorkeling.

Along the way, you'll be cruising with travelers of all ages and you'll have access to Royal Caribbean's water sports activities, diverse dining options and lively evening entertainment.
