Royal Caribbean’s Voyager Class is a family of five, and 3,114-passenger Adventure of the Seas — the “middle child” — has perhaps the most appropriate name, given the multiple heart-pounding activities on board. Passengers can skate (on ice in Studio B or wearing rollerblades on the outdoor in-line track), rock climb, and even say, "I do" in the Skylight Chapel. The outdoor movie screen was added during the ship's 2014 dry dock, and with another refit coming in 2016, who knows what added attractions Royal Caribbean has in store.
