When I went to school in the 90s, as a freshman, we had 3 students to a single room (at least mine). 1 bunk bed, one single bed. I remember it was normally 2 to a room but we had overcrowding issues at time time. It was fine, I didn't have any issues with my roommates, but I didn't hang out with them much either. When you're that close, you learn how to get along with anyone. We were freshman and didn't spend a lot of time in our room anyway. We would study in the library and hang out in our friend's rooms, or outside. I moved to off-campus housing after a couple of years and kinda regretted it. Our dorm was men on the bottom two floors and women on the top two floors. It was a lot of fun, I remember the time fondly.
