Yes, Janie, they are. In fact, one or two of them will no doubt be designated venues for workshops. They're not HUGE spaces, but big enough to do the trick. They are furnished with, as I recall, couches and armchairs, but there are folding chairs readily available in each building (or so we were told), and should be just fine.
The Retreat Center building has, in addition to a large open room (which will serve nicely for registration and silent auction and craft-and-CD sales) and a small kitchen, a large lounge which will be an excellent space for large workshops. All in all, I think it will do very well.
Just a little over two months to go!
