Where can you prowl the winding streets of an old-world-style city, explore a rain forest, and pay an eerie nighttime visit to a bay that glows in the dark, all without leaving the United States? Only Puerto Rico offers historic Old San Juan, the teeming, colorful El Yunque Rain Forest, and the hauntingly beautiful La Parguera bioluminescent bay. Oh, and there's also the world-class beaches if you insist on doing nothing much at all.
Get There: Round-trip flights from New York to San Juan on JetBlue start at $335.
Stay: Embassy Suites Dorado Del Mar Beach & Golf Resort, just outside San Juan, includes an 18-hole Chi Chi Rodriguez-designed golf course built along the rocky cliffs and jetties of Puerto Rico's Atlantic coast; complimentary cooked-to-order breakfast is included (201 Dorado Del Mar Blvd., Dorado, Puerto Rico, embassysuites.hilton.com, doubles from $159).
