Ceiba del Mar, Puerto Morelos $$$$
Concierge.com's insider take:
In need of some peaceful pampering? Travel 20 minutes south of the Cancún airport to this serene hideaway where masseurs work magic on knotted muscles, butlers slip morning coffee into a niche by your door, and hammocks sway gently outside the 88 rooms and suites. Ceiba eschews fussy design in favor of solid handcarved furniture, cloudlike beds covered in white linens, and sky-blue pillows and accents. The two swimming pools are free of blaring music and shrieking kiddies (no one under 16 is allowed on property), and though all the essential techie toys—iPod docks, Wi-Fi—are at hand, most guests ditch their laptops in favor of scuba gear for the offshore coral reefs. Two restaurants, a large spa, complimentary yoga classes, and trails through adjacent mangroves provide sufficient diversion for guests seeking extreme relaxation. Splurge on one of seven ocean-view penthouses with whirlpools on private rooftop terraces.
