Atop the main beach and in the center of the action, the Omni is the focal point of Puerto Aventuras, but its low-key luxury is a cut above the town's other resorts. Small for a full-service facility, it feels spacious and peaceful. Rooms have sitting areas with a plasma TV, plus terraces with hot tubs and views of the ocean, pool, or marina. There are plenty of spots to get your feet wet—including two connecting pools, a swim-up bar, a children’s pool, and the beach dotted with Bali beds. A 9-hole golf course is within walking distance, and the marina is just around the corner. Breakfast and a newspaper arrive at your room daily by way of a cubbyhole, to avoid disturbing your slumber.
