We have three bedrooms plus a loft that we use as a bedroom. We have a set of bunk beds, a queen bed, a full sized bed and a toddler bed (not to mention the king size bed that Dad and I sleep on), and yet come summer time this is pretty much how the kids sleep every night. They love to sleep together in the same room. Sometimes there are disagreements about who gets the bed, but they are usually pretty good about working it all out. And most of the time they really don't mind sleeping on the floor as long as they can sleep together.
