What: A two-story villa of a spa tacked onto the buzzed-about Viceroy resort, with a small saltwater infinity pool and treatment suites with private terraces.
The look: Organic, slightly Seussian: Curved, silvery loungers sit next to black-and-white-striped tables atop a silver travertine floorbut they're easily outdone by the Caribbean vista beyond.
Who goes: Manhattan financiers, Victoria's Secret models, and celebs.
The treatment: The 90-minute Raindrop Harmony, a revved-up Swedish massage with reflexology and stretches that'll make you feel slim enough to join Sandra Bullock et al on the beach.
P.S.: Book the Plumeria suite for its steam shower, tub, and seascapes.
