Has anyone tried putting a king size inflatable mattress on the floor of the 1 bedroom next to the king size bed? Last time we stayed in a 1 bedroom we put the kids, then ages 3 and 4, on the pull out couch in the living room and half way through the night they ended up in our bed. So I figure if we just put them on the floor on an inflatable mattress we wouldn't have them in our bed. I am asking about a king size since we currently own one we won't have to go buy another size. Hopefully this won't be an issue for too many more years. We are hoping to be able to reserve a 2 bedroom in the future and put the kids over there!
