If a couple of showpieces were ever needed to illustrate the major advancements of human technology, Mariner of the Seas would be one of them. With a total length of 1,020 feet, a weight of 138,000 tons, and a capacity to hold 3,114 passengers, you can bet Mariner of the Seas has something for everyone. Part of the Voyager class of ships, which represent the highest space-per-guest ratio in the cruise market, this spectacular ship was designed with enhanced staterooms, expanded dining options and state-of-the-art recreational facilities like a rock-climbing wall, ice-skating rink, and basketball court. Mariner of the Seas sails the Eastern and Western Caribbean round-trip from Port Canaveral, Florida.
