Concierge.com's insider take:
Surrounded by 125 acres of preserved mangroves and white-sand beaches, tiny Tiamo makes you feel as if you've landed—plop—on an island in the South Pacific, instead of the Caribbean. An extensive renovation, completed in 2010, transformed the resort from eco-friendly to eco-luxurious: The canvas tents have been replaced by 11 downright decadent solar-powered cottages built with reclaimed driftwood and glass. Not that they look it. Expect modern island design, including a South Beach–style outdoor lounge right on the sand, where you can sip rum punch made with organic fruit grown on the property (the restaurant is likewise stocked by the hotel's garden). In keeping with the stewards-of-the-island theme, a "nature concierge" leads guests on snorkeling adventures and kayak trips to learn about the plant, animal, and marine ecosystems of Tiamo. Bonefishing and diving trips are also available. But for the most part, this is a place where couples come to lounge around in stylish, uninterrupted privacy.—Leigh Newman
