We plan on bringing an air mattress for my DGS to use even though the room has 2 queens. He's a "sideways sleeper" and my son--HIS DAD--won't sleep with him and at 11 is too old to sleep with gma. I keep telling my son it is his fault--instead of buying him a single/twin bed for home he bought him a double so now the child is used to being able to "sprawl" when he sleeps 
Will my ecv and an air mattress fit? I was thinking of asking them to take the desk out. Do you think they would do that so I don't have to rearrange it or can I fit an air mattress and ecv into the room, even if tight?
