The 130-room Royal Suites Yucatan is the smallest, quietest, and most luxurious resort in the five-resort Grand Palladium Riviera Maya complex, and the only one for adults only. Located along the beautiful Akumal coastline between Tulum and Cancun, this upscale resort gives guests an all-inclusive experience with more food an drink options than you can count on both hands, all-day and night activities, soft sand and coral rock beaches, wildlife, a huge hydrotherapy-based spa with gym (access for a fee), and relaxing nature-filled grounds. While Royal Suites guests get full access to the features at the sister resorts, the reverse is not true. The rooms have much more contemporary decor than what is found at the sister properties, and the lagoon-facing Mayan Suites here are among the nicest accommodations in the entire complex. Just note that the property is sprawling and it's a trek to the beach, though shuttle service is available.
