In the Caribbean’s Windward Islands, a string of some 600 islands and islets dot the sea between St. Lucia and Grenada. It’s a paradise for yachters, where you can drop anchor off an uninhabited island and live out your Robinson Crusoe fantasies. A handful of these islands are home to resorts, including the private Palm Island, first leased to an American couple in 1966 for $1 per year. They established the ten-room Palm Island Beach Club, which over the years has grown—though there are still only a total of 43 guest rooms on this single-resort island.
