In addition to ancient ruins, the lush jungle region features beaches, underwater caves and an immense barrier reef (second only to Australia’s Great Barrier Reef) inhabited by rays, turtles and even sharks. A waterfront wedding is a must; choose from seaside venues such as Victoria House and Grand Caribe, both of which offer customizable packages and onsite wedding coordinators. Or say I do at the island’s newest hotel, El Secreto, which opened in October 2012 with 13 thatch-roof villas, a spa and easy access to the region’s best diving and snorkeling sites.
