I went to Grand Spa last week... I like going there because it's a great deal at $10 on weekdays and the facility is pretty good.
Anyway they seem to be actively trying to prevent inappropriate activity there. The doors to the sleeping room (back off the TV room) and the other warm floor room (across from the lockers) have been removed, and the sleeping room mats have been replaced with recliners, and another TV has been put into that room. At least both rooms are dark, though.
But it's annoying because none of them are really quiet with the missing doors.
Also, an attendant seemed to check the steam room every 5-10 minutes.
A friend of mine was there earlier this week, though, and didn't notice an attendant checking the steam room. However, he did tell me that they seem to have raised the weekday price to $15. Hmm.
