Get the experience of visiting two island colonies in the same 37 square miles. Saint Maarten/Saint Martin's spicy marriage of Caribbean, French and Dutch cultures matches its physical diversity: the island is both urban and untamed, with rain forest-like landscapes, white beaches, and amazing caves and wildlife.

Cartagena, a gorgeous fishing village on Colombia's Caribbean coast, has excellent beaches, a historic old town (that's entirely walkable) and beautiful colonial architecture. It's also one of the safest places in the country, so it's no wonder it's a popular port of call for cruise ships. Need a break from exploring the cobblestone streets? Stop at an outdoor cafe for excellent pastries and people-watching.

Isla Mujeres offers a wide variety of tempting options for beach lovers, and is a relative bargain. Snorkel with tropical fish amid coral reefs, skim the blue waters by kayak or boat, or windsurf along the shores of soft, sandy beaches. On land, you can sunbathe, dine on seafood, dance to Latin rhythms, tour on a moped or belly up to the bar for fresh, delicious drinks.

Sunny Cancun has much more to offer than its party-town reputation might suggest. Plenty of gorgeous, drama-free family resorts cater to folks who want to experience the tropical Yucatan climate. There are significant Mayan ruins here, such as El Rey and the Yamil Lu’um, a crumbling tower of pale gray stone. Learn more about this ancient civilization at the Museo Maya de Cancun. For a literal taste of Mexico, take a tour of the Museo Sensorial del Tequila.

Myrtle Beach is all at once a spring break destination, golfing destination, retirement community, and family vacation spot. Take in a foot-stomping show at the Carolina Opry, or cheer on your favorite knight at Medieval Times. Mingle with the fishermen of Springmaid Pier, then stop for ice cream along the boardwalk. Shop and dine at one of the area’s many outdoor entertainment complexes, or simply explore the many beaches of the Grand Strand – all with a personality of their own.
