You're right, it is a very small cramped room, only room for one 'butt' at a time.

It's in sort of an 'L' shape (with the short leg of the 'L' near the entrance), so someone could be dealing with the washer(s) and another in the entrance loading/unloading a dryer.
I checked back a couple times during our stay, and lucked into a quiet afternoon there while DH and the kids napped. Some ladies were just finishing up their stuff, so I dashed back to our room and grabbed our laundry. The drying cycles seemed to take forever, not sure why, so I wound up being there for a long time, even though I got 3 loads washing at once, then drying simultaneously.
The laundry is not where I wanted to spend the afternoon (especially when it was hot out!), but it has a bench outside, so I just brought a paperback book and a cold drink with me and read while I waited.
I thought the laundry detergent and dryer sheet were way overpriced, so next time I'll bring little ziploc bags (pre-measured) from home. I'm not sure I'm remembering right, but I think the soap was $2/load, and the dryer sheet was $1 or $1.50.
