According to the student, most people leave the space around 2am, with everyone gone by 4am. There is no one on duty there at that time, except for security guards who come to check in around 6am. The room also got very cold, he said.
On a side note, apparently security and library administrators are talking about installing a few more security cameras, as well as possibly a vending machine. The lack of food is one complaint students have had so far, as well as a lack of chairs and tables (most tables have the Media Cloisters computers on them).
