Used to work there...had a couple weird experiences:

1. Was walking through the spa/pool area one night. Heard a giant splash in the pool. Went running back there assuming the lifeguard like slipped in or something. Water was moving, but no one in there.

2. Was closing up the amenity area one night and locked the pool/spa area. Went in to clean up the locker rooms and after I came out of the men's, the area was unlocked again. Went back over, locked the door again, and checked the women's locker room. Came back out and the door was open again. No other staff around and no one on the locked side of the door.

3. We would set up the poker room to look like a game was being played. One day I set it up, walked out to check the pool tables, went back in and the poker table was completely cleaned up.

I've heard other stories from residents as well... Also, hated having to go to the basement that has tunnels connecting to the other buildings.
