For more than 40 years now, Mustique has been regarded as the ultimate getaway for the rich and famous — because in addition to its tropical splendor, Mustique is also very, very private. The 1,400-acre island is owned by the Mustique Company, a consortium made up of the island’s 50 resident villa owners. Over the years, these have included Mick Jagger, Bryan Adams, Tommy Hilfiger, Felix Dennis and Princess Margaret. They’re drawn by Caribbean paradise, of course, but lots of islands are pretty. This one is also very rich, very exclusive and — did I mention? — super private. There are few places left in the world that are as safe from the prying lenses of paparazzi as Mustique, which is no doubt why Prince William and his fiancée, Kate Middleton, recently vacationed here.
