RIVIERA MAYA, MEXICO

This 75-mile stretch of Mexican coastline south of Cancun is renowned for its beautiful, uncrowded beaches, all-inclusive resorts and ancient ruins. The whole family can enjoy the area's many natural wonders, such as the Great Maya Reef, where you can see tropical fish and coral while snorkeling or scuba diving in the clear-blue waters of the Caribbean. Or take a jungle tour, swim in a subterranean cenote (freshwater-filled sinkhole) and watch sea turtles swim ashore. Be sure to check out the Xcaret theme park with a great waterpark.

A favorable exchange rate will help stretch your dollar. We recently found a room for four at the all-inclusive, five-star Bahia Principe Resort in Tulum for less than $150 a night. This resort has a kids clubs for children ages 4 to 12, so you can keep Junior entertained while you explore the nearby Mayan archeological sites.
