Titanic: The Artifact Exhibition at the Luxor holds more than 250 objects recovered from the wreck site two and a half miles below the surface: personal effects, ship fittings, unopened perfume vials, currency, china still stacked as it was packed. It is a permanent installation and the largest collection of Titanic artifacts on public display anywhere.
The exhibition rebuilds parts of the ship around them, including a full-scale section of the Grand Staircase, first-class and third-class cabins, and a corridor held at the temperature of the North Atlantic that night. The largest object on display is the Big Piece, a fifteen-ton section of the ship's starboard hull.
Each ticket carries the name of a real passenger, and you find out at the end whether you survived. Allow about ninety minutes. A combination ticket with Bodies: The Exhibition next door is sold at the box office only.
