Long Beach, CA
In the 1930s, the RMS Queen Mary was the ultimate luxury liner: big names of the day like Winston Churchill, Greta Garbo and Clark Gable all journeyed across the Atlantic on her majestic decks. When World War II broke out, the Queen Mary was painted grey and re-dubbed the “Grey Ghost” to ferry soldiers to the frontlines. Today, you can find her docked off the port of Long Beach, CA, where she now serves as a floating hotel. But before you book, beware: the ship’s 1,001 trans-Atlantic crossings of yore were accompanied by 49 recorded deaths. Today, as many as 150 different spirits may still call the Queen Mary home. Some notable residents include a crew member who was crushed to death by a watertight door, a woman dressed in all-white who dances by herself in one of the luxury suites, and several adults and children in 1930s-era garb whose apparitions have been spotted wandering the pool decks. Watch out for drastic temperature changes, slamming doors, knocking, screams, lights flickering and children crying -- all aboard a ship that’s earned its reputation as one of the most haunted structures in America.
