The El Dorado Royale is an adults-only resort with a whopping 450 acres of tropical jungle along the Riviera Maya. For walkers, be prepared to exercise the legs here, otherwise jump on one of the many golf carts scooting from one end of the property to the other. Staff members go out of their way to keep guests smiling, and these free rides are a good way to experience the manicured grounds. There are 13 pools in total -- an important aspect, as the ocean bottom is too rocky for most to enjoy. However, the mile-long sandy beach is still suitable for games, strolling, and dining (romantic candlelit dinners are possible). For other options, the resort calls itself a "gourmet" all-inclusive, and offers a dizzying array of restaurants, as well as bars, nightlife, spa treatments, and on-site activities to keep everyone busy. When in need of an escape, the tour desk arranges off-site excursions, or guests can take a shuttle service to visit Cancun or Playa del Carmen. There are three total sister properties in this area, and the Royale is the most basic -- though rooms still feel luxurious with white-linen-draped canopy beds, balconies or terraces, walk-in showers, Jacuzzi tubs, bathrobes, and stocked minibars. The resort is attached to the newer Casitas section with additional amenities such as outdoor showers and private plunge pools.
