It’s sunshine all the time in the Caribbean, so grab your flip-flops and enjoy a cruise to remember through the islands. Uncover the secrets of Old San Juan — stroll this historic, walled neighborhood brimming with 16th- and 17th-century Spanish colonial buildings. In lush St. Lucia, hike at the base of the Piton peaks or take a dip in the deep-blue Caribbean Sea. And keep your camera ready when in St. John’s to photograph the only working Georgian dockyard in the Eastern Caribbean as well as the breathtaking views over sailboat-studded English Harbour.
