Location: Eastern Caribbean, Bahamas Out Islands
Size: Less than two square miles
A tiny link in the chain of Exuma Cays, this gem lies 250 miles off the coast of Florida in the Bahamas' famously clear turquoise waters. Many of the Exhumas are private (Johnny Depp owns one) or ultraexclusive, but Staniel Cay is an exception. Here, you can stay in a cottage on stilts over the ocean for only $165 per night. Everything but the price seems top-shelf.
Go for the all-inclusive package ($176 per person per night) at Staniel Cay Yacht Club and get a waterfront cottage, all meals, and your own 13-foot Boston Whaler during your stay. Cruise to a deserted beach or see the swimming pigs at Major Cay. Snorkel at Thunderball Grotto, a hollowed-out island and the filming location for James Bond's Thunderball.
The yacht club arranges shared charter flights (two-and-a-half hours) from Ft. Lauderdale on Watermakers Air starting at $200 per person one-way.
