Karosta Prison Hotel
Located in Latvia, this haunted hotel allows you to pay them to be a treated as a prioner during your stay. Before Karosta was a hotel, it used to be a military prison that was used by both the Soviets and Nazis. Many people died there, mostly by gun shot to the head, so this place is considered haunted by many people.
Before you can be a “guest” at the hotel, you have to sign an agreement that allows the hotel to treat you as a prisoner. This includes living in an iron cell, sleeping on an old mattress, letting the guards yell at you, etc. Failure to do any of this will result in punishment, which means that you have to do chores around the hotel, like cleaning.
