Castaway Cay, formerly Gorda
Cay, is an ultra-tidy 1,000-acre splash of sun and sand located near Great Abaco
Island. Owned by the Walt Disney Company, the island is used exclusively for
passengers of its cruise line -- though alert cinephiles may also remember it as
the spot where Tom Hanks finds his mermaid (Daryl Hannah) in "Splash." Before
becoming one of the cruise line's most popular ports of call, it was a haven for
pirates and, subsequently, smugglers. (An airplane runway that runs down the
spine of the island is no longer used, though it remains a busy thoroughfare for
bicyclists, pedestrians and trams.)
