Navigator of the Seas. A cruise ship or a work of art? Not only does it sail effortlessly through the waters, it contains some of the cruise industry's most amazing features - a rock-climbing wall, a basketball court, an ice-skating rink and an in-line skating track. Dare we say there's more? What about a five-story theatre, a casino, a miniature golf course and a spectacular three-story dining room? This 138,000-ton nautical wonder has it all.
