Along with adding to the Family beach, Disney had to make the dock bigger.

The family beach is larger now to accommodate the new larger upcoming Disney Cruise Line Ships. The teenagers didn't use the teen beach so Disney decided to add to the family beach. There used to be a teen beach but it is now part of the family beach. The island features two beaches:A Family Beach and an Adult Beach. The island features buildings that look like they were improvised after a shipwreck. Disney's private island in the Commonwealth of the Bahamas is 3.1 by 2.2 miles in size and features a post office with its own unique Castaway Cay postmark. Reserved exclusively for Disney cruise Guests, Castaway Cay is a port-of-call paradise on Disney Cruise Line Bahamian and Caribbean cruise vacations, where you enjoy such tropical leisure as snorkeling, boating, swimming and old-fashioned sunbathing. The island will soon be the port of call for the new Disney Ships called Disney Dream(2011 sail dates) and the Disney Fantasy(2012 sail dates). The island is a port of call for Disney Magic and Disney Wonder. Of the island's 1,000 acres, only 55 have been developed for Guest use, leaving the remaining land unspoiled and untamed. It took builders 18 months to perfect the rustic, 'castaway' landscape and motif that lend the pristine scenery additional charm. More than two centuries later, The Walt Disney Company purchased the island-used as a location in the classic 1984 Disney film Splash-to create a private paradise for Disney Cruise Line Guests.

Formerly known as Gorda Cay, Castaway Cay is located amid the Abaco Islands in the northern Bahamas, an area first occupied in 1783 by European settlers in exile from the American Revolution.
