Silversea This 10-ship line offers a premium cruising experience – at an appropriately premium price. But if you want to see the Caribbean in fine style, you’ll be hard-pressed to do better than 540-passenger Silver Spirit’s 13-day cruise to Dominica, St. Barths, Grand Turk, Barbados, Puerto Rico and St. Lucia, which departs Fort Lauderdale on December 22.
