6. Castaway Cay, Bahamas

Castaway Cay in the Bahamas is another private island that was made famous by a movie, featuring as it does the beach where Tom Hanks first met Daryl Hannah in Splash. Castaway Cay is an exclusive port for Disney Cruise Line ships. Made for tourists, the Disney-themed island appears like a castaway community; the buildings look as if they have been improvised after a shipwreck. There are three beaches on Castaway Cay: one for families, one for teens, and another exclusively for adults.
