People tend to check in during these times:
This place has a really F'd up visitation system. Don't come here unless you want to deal with it
The most beautiful women reside here
Wow the RAs here are really cool and awesome!
Don't you dare try and sign out your guest at 12:02 because you'll get lectured by a pissy security guard (in which you you paid the salary of) about how you need to learn to read a clock.
Make sure to bring a valid ID for visitation
