San Diego, California
In addition to being home to a world-class zoo and aquarium, San Diego is a laid-back navy town that is the closest U.S. city to Mexico. Great Mexican/American cuisine, Spanish-inspired architecture and what some consider the best weather in North America, make San Diego a destination unto itself.
Cabo San Lucas, Mexico
