What do you call a spa that combines Mayan healing philosophies with Far Eastern traditions? Mex-Zen? Mayasian? With a nod to both its corporate lineage and its Yucatán Peninsula home, this 25,000-square-foot facilityeight treatment rooms with private showers, two couples suites, and three outdoor treatment palapas on the banks of a cenoteoffers a novel fusion of rituals. Lush tropical beauty contrasts with tranquil Asian design, and unique elements abound: The vitality pool has two submerged lounge chairs (where water jets give you an acupressure massage), and in the mandala garden, you can pick a flower or herb to use in your treatment. The two-hour Mayan Tzolkin Ritual ($317) includes a footbath, heated herbal compresses, and a massage with yoga stretches (90-minute massages, $235).
