Famous for being the setting for the Marilyn Monroe film, Some Like it Hot, room 3502 of the Hotel Del is the source of some extreme haunting activity.
The spirit is believed to be Kate Morgan, a woman murdered by her cheating husband. She can be spotted wandering the hotel wearing a black dress. This room is so freaky that the hotel doesn't let anyone use it unless all the other rooms in the hotel are filled. Once it was even sealed off because there was so much poltergiest activity going on in there.
