I lived in both hall style dorms with bathrooms down the halls and suites with their own bathrooms. No socializing happened in the halls of suite style dorms. You might get some, if decent communal social spaces are created. In the hall style dorm we used to leave our doors open and people would all get together to go out for drinks or pizza. Or people would just wander down the hall to see if there was someone to talk to. For some reason with the suites, no one ever left their doors open.
