Oooh, this one sounds kind of creepy. It's a Haunted Las Vegas Tour.
Here you can go on a tour to see the haunting grounds of Liberace, Redd Foxx, Bugsy Siegel and Elvis. Creator of these tours, Robert Allen has consulted with a paranormal historian and an author of a book about hauntings in Nevada and according to them there has been paranormal activity in more than 21 places. Yikes! lol.
The tour will also take you to the "Motel of Death" where several celebrities have died and to another place where it is claimed to be haunted even after exorcises have been performed.
The tours run three hours. Children 13 and older can attend but they must be accompanied by an adult. Video cameras and still cameras are welcome.
