if it's set up like a large dormatory, with shared kitchens and bathrooms and communal areas it would incorporate more character interaction. I know when I was in a dorm each floor had a living room, a private bathroom with signs on them basically saying no sexing in hurr, and a communal bathroom and even though I hung around in my room a majority of the time, I ended up forced to interact and make friends just due to proximity/running into them all the time.
