A consortium of homeowners oversees Mustique and ensures that everything stays exactly the way it is, so it comes as no surprise that this Caribbean island has been able to maintain its reputation as an exclusive hideaway for the ultra rich. Those who are not a lucky owner of a villa can stay at the dreamy Cotton House. The heart of this 17-room gem is a sugar mill and an 18th century storehouse with its famous Great Room where villa owners meet once a week to enjoy glamorous cocktails.
