It’s not just for spring-breakers. Cancun, with its golden beaches and perfect climate, is the premiere coastal destination in Mexico. And while there is certainly a 365-day party available for college students, resorts cater well to families and to those seeking solitude. This Yucatan paradise is also the gateway to the ruins of Tulum and Chichén Itzá.

U.S. citizens still need to jump through a few hoops to visit Cuba, but as visitors from around the world know, this island offers some amazing opportunities for cultural exchange. Havana is a mix of old-world architecture and of-the-moment culture. Head out of the capital city to the small town of Trinidad to see more Spanish colonial architecture. It’s a UNESCO World Heritage Site and a fantastic home base for a visit to the Valley of the Sugar Mills, a pocket of land that formerly served as the centre of Cuba’s sugar industry.

The Dominican Republic lies in the same waters as Cuba and Puerto Rico, taking up the eastern two-thirds of the island it shares with Haiti. Offering a lush interior with a mix of caves, Victorian gingerbread houses and the lore of pirates, plus 900 miles of coastline along its brim, island highlights include riding a cable car up Mount Isabel de Torres and basking on stunning Saona Island. Oh, and did we mention the D.R. is family-friendly, has just about perfect weather and is affordable?

There's more than one way to enjoy the spa experience in St. Lucia. One is to book a treatment at any of the luxury spas or resorts on the island. The other is to visit Sulphur Springs, inside the bowl of an extinct volcano, where you're welcome to try a volcanic mud bath or the 31°C/88°F Roman bath.
