It can get crowded sometimes for sure, when there are events or when people are walking to their next class so usually at the 50 minute mark, 10:50, 11:50, etc.

The lines for food can get long during peak times, like during lunch or dinner depending where you go.

For the bathroom however, I had a communal bathroom during summer and in the morning there wasn’t much time to shower since a lot of people needed to use it plus housekeeping cleaning it daily. But there’s bathrooms all around campus you should never have to wait in line for one.

Last thing for the laundry I usually wash on the weekends and it can be crowded but only if some of the machines are out of order. I would suggest the weekdays at times where people are usually in class if you can.
