I have noticed a lot of folks saying they use air mattresses at the value resorts. We have not used air mattresses, but had used a kids cot. Our first stay was at ASMo and we placed the cot between the two beds. Second stay was at POP and placed the cot between the bathroom wall and bed. When folded up, we were able to fit it in a suitcase for air travel. Our daughter has outgrown the kids cot, so we purchased an outad cot in a medium size. When taken apart if is smaller than the folded up kids cot and it is quite a bit lighter. It's the same width as the kids cot was, just longer. I think it would take up less floor space than an air mattress, plus don't have to worry about leaks. Only bad thing is it looks like it has over doubled in price since I bought it a couple months ago.
