If you have to stay in a one bedroom, ideally I'd recommend getting an air mattress. However, in a pinch (or weekend trip), we've taken the sofa cushions off of the pull-out couch, put them on the floor and stretched an old twin fitted sheet (brought from home) over them. Obviously the sheet doesn't fit perfectly and I'm not sure i would recommend this for an extended stay...but for a younger child, it's better than the hard floor. Didn't hear a single complaint from my dd when we did this.... However, as the previous poster said, the living room does get a bit tight.... Good luck and have fun!!
