Clearly Monokuma had the right idea installing chain guns above the dress rooms to the pool area. You buncha pervs. I'll just have to squeese two people in with Shona, since her armor makes her impervious to your lust. >: C
Wait the rooms don't have their own bathrooms or showers?
The rooms that the patients are staying in are going to be like regular hospital rooms, except small enough for one person each. Every room has a stand up shower and a toilet, but they do not have a fully functioning bathroom. Your characters will sleep on hospital beds surrounded by medical equipment. It's a patient's quarters, not a student dorm. that's not to say the rooms don't have some yet to be revealed features.
If you were pointing out that I didn't specifically draw the rooms, it's because I'm more or less copying the type of map style we see in Danganronpa. They didn't draw everyone's bathroom in there either.
