I have to tell you, we just stayed at YC with me, DH, three kids (20, 17 and 17, two girls, one boy) in one room. My son did not fit on the daybed, so we brought an aero bed for him. The kids slept one on bed, one on daybed and one on aero bed. No problems. We just put the aero bed in the corner in the morning. The bathroom thing is overrated. We had absolutely no problems. The double sinks are outside the bathroom. So two people can get ready outside while one showers. You just have to be organized.
