Castaway has proven so valuable to the brand that Disney is investing between $250 million and $400 million to develop a 700-acre property called "Lighthouse Point" on the Bahamian island of Eleuthera.
The cruise line spent more than $16 million on developing the island into a private beach resort, where cruise guests can go snorkeling, horseback riding, and swim with stingrays.
Carnival CEO Josh Weinstein said on a March earnings call that the cruise line is working to "further leverage and monetize" its land-based assets this year.

Many of the cruise line's North American cruises stop at Perfect Day at CocoCay. And this year, Bayley thinks the getaway will see two-and-a-half to three million travelers.

Perfect Day at CocoCay is lined with complimentary beaches, pools, and food stands.

However, many of the more desirable amenities — like the beach club, water park, and cabanas — come at an extra cost.

With all of these paid amenities, it's no surprise the island's financial returns have been "exceptionally high and significantly above its targeted returns," Naftali Holtz, Royal Caribbean Group's CFO, told investors in February.
But CocoCay isn't complete yet. In 2024, Royal Caribbean will unveil an extension of the private island: Hideaway Beach, an adults only section with a pool and private cabanas.
