I've done two other things:
1] I called my LQS's and asked if I could use thier tables when a class is not in session. Since I shop there, there was no problem.
2] I belong to a quilting group that meets at a local church and just used the tables, with permission, in the other classroom or Fellowship Hall, since there wasn't another group meeting at that time. One of my auilting buddies even helped me lay it out and it went really fast.
