O/night & slideout
I wouldn't slide out my living room or kitchen. I probably would consider sliding out the bedroom, since its just barely usable otherwise. The whole point is to not cause WalMart any grief. So before bedtime I would assess whether I could do it without affecting anyone (plenty of room for anyone already there, plus new arrivals, plus customers), and if I did put it out, bring it back in first thing in the morning. Plus, I would have already have asked the manager if it was ok to stop there, and put out the slide, while I was making a purchase...
