At one time a less-than-appealing place to visit, Long Beach has transformed itself into an upscale tourist resort, with many waterfront attractions, including a new, state-of-the-art aquarium with a fabulous shark exhibit, two excellent art museums, charming shops, public golf courses, the annual April Grand Prix international auto race and lots of recreational activities along its eight-mile stretch of beach. But for everyone, a visit to this floating hotel and museum is a must on any trip to Long Beach. Others, particularly the younger set, are entranced by the spine-tingling haunted ship stories on the nighttime ghost tour. For some, a tour of the Queen Mary, docked here since its retirement in 1967, evokes waves of nostalgia for the days of the huge ocean liner with its opulent rooms, 1930s deco décor and teakwood decks.
