We did POP last August.
DH and I each took the double beds.
both DS's used the air beds. One son put his bed in front of the window, ( we just moved the table a bit) #2 put his at the foot of my bed in front of the connecting door. When we woke up in the morning the beds were stood on end in front of the connecting door. Everyone was fine with this. With small ones you can definately do it. Especially if money matters. You wont' be in the room for long. Go, Have fun
