Our Fort Lauderdale roundtrip voyage begins with two relaxing days at sea to enjoy Crystal Grace’s onboard offerings – from her sumptuous spa to convivial pool bar. Francophone St. Barts is our first port of call, to see and be seen in the glamorous boutiques of Gustavia; followed by Roseau, the capital of Dominica, where you can hike through lush jungle and swim in refreshing waters. Then buzzy Bridgetown delivers us to powder sands that celebrities love to bask upon, before the soaring twin volcanic cones, the Pitons, signal we are approaching Castries on Saint Lucia. In Basseterre, Saint Kitts, bask on super-soft sands and discover French and British colonial architecture, and in Puerto Rico’s capital San Juan, stroll colorful cobbled streets and sip on piña coladas – the tropical cocktail was invented here in the 1950s. Another two sea days offer plenty of opportunity for rejuvenation before we arrive back in sunny Fort Lauderdale.
