Spring Break for Grown-ups

With a bunch of flights from the U.S. (and no need for a passport), Puerto Rico has to be one of the easiest places on earth for an American to escape to—an observation that has not gone unnoticed by the ready-to-rage 20-somethings who throng the beaches and big casino hotels surrounding the capital of San Juan. Kelly Regan, editorial director of Frommer's Travel Guides, suggests you instead check out the southern coast of the island—home to what she says are "the most beautiful and least crowded beaches, like Cana Gorda, where Puerto Ricans vacation in the summertime." Regan also recommends Ponce, a well-preserved 18th-century city that gives you the colonial flavor of San Juan without all the crowds.
