Royal Caribbean International today announced winter 2013-14 Caribbean cruises aboard the Oasis of the Seas, Allure of the Seas, Independence of the Seas, Freedom of the Seas, Navigator of the Seas and Serenade of the Seas, offering 140 sailings on 31 distinct itineraries that will call at 20 different ports.

All six ships will offer what the cruise line calls “the most contemporary vacation,” with Independence of the Seas, Freedom of the Seas, Navigator of the Seas and Serenade of the Seas all having completed their revitalization and enhancements to deliver more delectable dining options, cutting-edge entertainment and a slew of modern onboard amenities that first debuted aboard the line’s Oasis-class ships. Winter 2013-14 vacations aboard the six ships are now open for booking.

“The Caribbean is our namesake, and no one can deliver the region like Royal Caribbean,” said Betsy O’Rourke, senior vice president of marketing, in a prepared statement.

The Oasis of the Seas and Allure of the Seas will continue to alternate seven-night Eastern and Western Caribbean itineraries. Sailing roundtrip from Port Everglades, the ships will call at Nassau, Bahamas, St. Thomas and St. Maarten on the Eastern Caribbean sailing, and at Falmouth, Jamaica; Cozumel, Mexico; and Royal Caribbean’s private beach destination Labadee, Haiti, on the Western Caribbean sailing.

The Independence of the Seas also will homeport at Port Everglades, and alternate six-night Western Caribbean and eight-night Eastern Caribbean itineraries.
