Although this beachfront property has been overshadowed by its newer neighbors, the location—amid 500 acres of lush jungle—is as alluring as ever. A crystal chandelier and marble infinity fountain vie for attention in the extravagant lobby. Junior suites have small sitting rooms, king-size beds, hot tubs, and ocean-facing terraces; in the more upscale Casitas Royale section, swim-up casitas have dome roofs and oceanfront terraces. Eight restaurants serve exceptional dishes. Despite the size of the resort, it strives to be eco-friendly by using solar water-heating systems, energy-saving air-conditioners, and recycled water; a 70,000-square-foot hydroponic greenhouse grows most of the vegetables served. There's free shuttle service to Cancún and Playa del Carmen for organized shopping tours.
