found them uncomfortable and thought the beds were smaller than a standard twin size bed (no idea if they were correct about that or not, they are all tall kids that sleep on bigger beds at home). the double bed was by far the most comfortable in the house, so much so that if we come back we will claim that bed and put one of the kids in the master bedroom. a/c- the system prevents you from setting it lower than 72 degrees. the claim is fear of freezing over the system. i live in texas and am quite sure that this is not a real concern at anything
