I never want to go back to a trailer...bedroom or not for the kids. Like any of the curtains or hollow doors provide that much privacy or quiet anyways. To each their own though...getting there and set up is half the fun now....not so before.
Personally, I think they should have redesigned the rear bath by keeping the washer/dryer and doing away with the shower. We've used ours a couple times, but not enough to warrant having it. I may turn ours into a linen closet
