I did the other night (my sore back could prove it). It was awesome. Just me and the girls in the fort all night (Neil tried to help my back by posting up the tent part and inflating an air mattress). It was awesome. They loved it. I love that we are OK with trashing our living room to let them set up every pillow in the house under the fort. I loved it too. I felt lucky to spend the night in there with them.
