Im almost positive this was it that I linked, it was a day my partner picked out. It was really cool. If you go, when you enter the area with the wood walls they have ropes up against the walls and a little carpet path that weaves through. Even though the ropes are no were close to the carpet you are supposed to stay on the carpet, dont walk on the floor. I got scolded.
