I got a bunch of small metal loops and riveted them onto the floor of the folding 1/2 of the tent, then ran shock cord (bungie cord) around the perimeter of the floor and then across on the diagonal.
It gives a nice handy place to hang towels and the like to dry. In your situation, you could then use it to hang a few towels as to act as curtains and save doubling up on the gear you are carrying.
I have a photo somewhere, but can't find it now.
