More than 250 artifacts of the RMS Titanic are on display at this 25,000-square-foot space at the Luxor. Among the truly incredible mementos excavated from the wreck of the sunken ship: an unopened bottle of champagne, a floor tile, a window frame, and a giant piece of the ship’s hull. Perhaps more impressive than the artifacts themselves are the full-scale re-creations of what guest quarters looked like on the ship—attending the exhibit gives you a sense of the difference in the experiences of a first-class passenger and a third-class passenger. Since it opened in the late 1990s, the exhibit has been seen by more than 25 million people, which makes it one of the most popular attractions in Las Vegas history.
