Leaving behind the palm-fringed metropolis of Fort Lauderdale, Florida, we spend two days at sea making the most of Crystal Symphony's offerings � from the sumptuous spa to world-class entertainment. Our first port of call is historic Cartagena, Colombia, where we overnight, leaving plenty of time to stroll the colorful streets and admire the stunning 16th-century architecture. We then embark on the exciting experience of cruising the Panama Canal, a feat of 20th-century engineering, before a day at sea brings us to Puntarenas on the Pacific coast of Costa Rica, and then across to Nicaragua, where you can watch the surfing at San Juan del Sur. Sample the coffee from one of El Salvador's famous plantations at Acajutla, before another couple of sea days bring us to Mexico for the blond-sand beaches of Puerto Vallarta. After two more days on board, we cross yet another border to the U.S. and our journey's end, sunny San Diego.
