I very seriously contemplated moving into Hoover one semester... I was going to bring a change of clothes, some ramen, ect and store them in an unused cabinet in the student room.
As it was I spent multiple nights in there... and sometimes they weren't even for academic reasons (In particular, KQ but even used one of the labs to play Wii on the LCD projector)
Spent quality time in Gilman Freshman year too... but far and away Hoover takes the cake
