If you're ever wondering aloud where the hottest mid-winter celebrations take place, those in-the-know might quietly respond, “St. Barts.” The island's luxe air of mystery and remoteness are part of what makes it a seasonal staple for jet setters and superyachts as they follow the sun to the Caribbean in winter. The festivities rage on until the St. Barths Bucket Regatta in mid-March, but what most visitors don’t realize is that the island is practically a year-round one, since the only time hotels typically shut is at the height of hurricane season (late summer).
