We are looking at the OGC Camp... it's run by Svetlana Boguinskaia, I believe, and is offered at different locations in NC, SC, Florida, etc.
www.OGcamp.com if you want to check it out. They don't have a "sleepover" camp, but if you aren't close enough to commute, they recommend the same hotel for the families. We have friends who live close to one, so we can stay for free. Has anyone ever been to this one?
