Florida's Southwest Gulf Coast contains a constellation of enticing coastal gems. Stunning beaches, including Fort Myers Beach, Tigertail Beach and Pensacola Beach, fringe the Gulf, down the I-75 from Tampa to Naples. Sanibel Island's shells attracts thousands. Cape Coral's waters are paradise for fly-fishing. Golfers adore spectacular courses in Marco Island and Naples. Glorious sunny days and deliciously warm turquoise waters beckon in this often overlooked corner of the Sunshine State.

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.

Key West has great nightlife—and a perfect cover story for someone who wants to enjoy it. A Hemingway fan simply must toss back a few at their hero’s favourite bar! You’re not reliving Spring Break, you’re immersing yourself in great American literature. Yeah. That’s the ticket.

This canal-laced city is a far cry from its rowdy, party image of the past. Today, following renovation and renewal, upmarket stores and restaurants have replaced fast-food stands and T-shirt shops. But the city's biggest draws are its stretch of gorgeous beaches, great swimming, nearly year-round sunshine and close-to-ideal climate. For great shopping, dining and nightlife, you can't go wrong at Las Olas Riverfront, a waterfront entertainment centre with top-notch clothing and jewellery shops, bars and free entertainment. The city has a host of family-friendly options, such as Everglades Holiday Park and the Museum of Discovery and Science. With the network of canals and waterways, boats are part of the Lauderdale lifestyle, and tourists can get in on the act by hiring a boat or hailing a water taxi. There's a lot to do here, but make sure and spend some quiet time just soaking up the sun or strolling along the beach at dusk.

At the shore in Miami Beach, visitors can swim, surf and jet ski in the warm and crystal-clear Atlantic waters. You can also nap on the white sands, work on a tan or simply watch the beautiful people, especially at South Beach, a favourite of models and celebrities.

You'll find crashing waves off Cabo's Pacific coast and sheltered, calm water on the Sea of Cortez. Given those options, Cabo has built a rare reputation for both excellent outdoor sports (big-game fishing, diving and kayaking, among others) and pure beach relaxation. Of course, there's also great nightlife. Cabo’s resorts, hotels and inns cater to everyone from honeymooners to families to Hollywood stars seeking a weekend getaway.

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?
