We have reservations for this summer at POR. We are a family of 5 and the room will technically sleep 5, however our three kids have decided that no one wants to sleep with the other. Do you think it is feasible to put a twin size air mattress so they each have a place to sleep on their own instead of two of them sleeping together in the other queen bed? I realize we would have to get up early and put it away so mousekeeping can service the room, but is there room for it?
