Focus your energies on discovering San Juan: Visit Old San Juan’s colorful restaurants and shops; walk along Ashford Avenue to see the capital’s current renaissance first-hand; and spend one afternoon hiking El Yunque. Cap off your visit by buying and smoking a cigar in the lobby of the El San Juan, where salsa is played nightly, and drinking a Piña Colada in the Caribe Hilton, where the drink was invented.
