Whatever you call it, it's a best-ofboth-worlds island: half French, half Dutch, yet all chic. Circumnavigate the 37-square-mile island and you'll find plenty of turquoise bays and marinas to nestle in for a stay. Visit casinos and dutyfree shops in Dutch Sint Maarten, on the southern half. Peruse the nightlife, nude beaches and beaucoup de bistros in French Saint-Martin, to the north. But don't be confused by this bisected island: It's all fun, fashionable and fabulous. Then, take a walk on the wild side. When the cruise ships pull in, escape the clamor of the crowds for untamed Île Fourchue.
