Thatch Caye in Belize
Situated along the Belize Barrier Reef just 25 minutes from the mainland via boat, Thatch Caye houses 13 villas with eight over-water bungalows. Head out for fly fishing and deep sea fishing excursions, or just lounge around in one of the hammocks that adorn the property. For about $7,500 a night the island is yours. It’s steep, but consider gathering 25 or so of your closest friends (or cast a vote with your boss for your next corporate retreat) for the best $313 a night retreat in the Caribbean.
