Dorms at my college were three stories: 1st floor for men, 3rd for women, and the 2nd floor depended on gender balance year to year. The year I lived on what was usually a guy’s floor, we had three urinals (useless but for the decorative element of large potted plants put in them by the RA) and a total of three toilet stalls in the communal bathroom. For 24 girls.
Drinking age was 21, and I was 17 when I started, so fortunately my college was the same as that of @washugrad:
Kegs were brought in every Friday and Saturday nights for university-sanctioned parties (Edwards Dorm Social! Pre-Med Honor Society Social! Swim/Dive Team Social!) For $2 (girls) or $3 (guys) you could drink unlimited beer, snack on pretzels and chips, and dance! You didn’t have to belong to the sponsoring group, just bring your ID and a couple of bucks.
Friday afternoons at 4 was movie comedy time. Into a dorm lounge was wheeled a giant TV (it seemed giant then; it was probably 60" :() and VCR so that 100+ students could watch Ghostbusters, Police Academy, Splash, etc., while drinking from one of the ever-present kegs supplied by Resident Life. I guess now that would be called “pre-gaming” with a handful of friends and Netflix.
Simpler, safer, more social times. It was not a large campus so everyone walked. And how inebriated can you really get on Busch, Schmidt’s or Ortlieb’s?
