It's easy to dismiss this old cruise ship/museum as a barnacle-laden tourist trap, but it's the only surviving example of this particular kind of 20th-century elegance and excess. From the staterooms paneled lavishly in now-extinct tropical hardwoods to the perfectly preserved crew quarters and the miles of hallway handrails made of once-pedestrian Bakelite, wonders never cease aboard this 81,237-ton Art Deco luxury liner. Stroll the teakwood decks with just a bit of imagination and you're back in 1936 on the maiden voyage from Southampton, England. Don't miss the streamline modern observation lounge, featured often in period motion pictures, and have drinks and listen to some live jazz. Kiosk displays of photographs and memorabilia are everywhere -- following the success of the movie Titanic, the Queen Mary even hosted an exhibit of artifacts from its less fortunate cousin. The Cold War-era Soviet submarine Scorpion resides alongside; separate admission is required to tour the sub. Buy both tickets and you'll also get a behind-the-scenes guided tour, peppered with worthwhile anecdotes and details.
