People tend to check in during these times:
Bring a sweater. Always really freaking cold.
Bring headphones, unless you like listening to other people's shitty techno.
Electronic chargers down low.
Great vending machine selection outside, even some (almost) real food that you can microwave in the same area.
Casino lighting !!!
Get a friend, some starbursts, and a study room. Eat the candy, play basketball with the wrappers, leave your score on the whiteboard. Pseudonyms only.
