Cayo Espanto, Belize
Each of the seven villas on tiny Cayo Espanto is spectacular in its own way, but only Casa Ventanas is built on a 150-foot dock over the gently lapping waves of the Caribbean. Windows and doors on all sides of the bungalow open to the brilliant sunshine and gentle breezes three miles off the Belize coast. Lights change colors to provide a different aspect on the marine life seen swimming below the glass floors.
