I just stumbled across the cutest idea. It is a card table playhouse. The playhouse just slips over the card table and can be taken off for storage. I need to make one ASAP for Wyatt, although the girly ones look so much cuter I think (and more fun to make!). The lady that made the one above sells them on Etsy, check out her store here. She has made some other really cute ones too, so make sure to look at them all. If I were a kid I would love one.
Here is another one that someone made:
