This peaceful adults-only resort, located along a white, sandy beach in the Riviera Maya, is geared toward romantic getaways (think honeymoons, anniversaries, and vow renewals). Each group of casitas has its own pool area that connects to a lazy river, and there are 13 public pools in total -- which is nice, because the ocean bottom is too rocky for most guests to enjoy. This all-inclusive resort offers a dizzying array of restaurants, bars, nightlife, spa treatments, and on-site activities to keep guests 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. Casitas have romantic touches such as wood-beamed ceilings, canopy beds, and outdoor showers, and the private patios can be curtained off for afternoon siestas on the day beds. For top-tier amenities, Presidential Suites have kitchenettes, hammocks, larger pools, and direct ocean views.
