55 West seems to be attempting to crack down on this as well. Two summers ago, the pool used to be packed every weekend with lots of people who don't live here and would bring beer pong tables, speakers, etc. last summer, they placed a security guard at the pool entrance that would check to see if you lived there. Residents are only allowed to bring two guests per resident. It really cleaned up the pool area and allowed all the residents to use it rather than ten residents and their 50 guests.
I think a lot of the issues with 55 West would be fixed if they just shut down the east entrance that anyone can get into or required key access to use the elevator and get to your floor.
