There is a 1:1 student/adult ratio permitted (not required) for individual enrollment classes. For group YES classes they only allow 1 adult per 5 children. His statement on that subject alone makes me doubt that he was as knowledgeable as he sounded. It was one of the things I was going to mention, but didn't, when you talked of forming a group. Someone would have to allow their child to be chaperoned by a stranger during the class. If you have 4 girls, and you add 6 girls from the DIS, you would only be allowed 2 parents. That means that you could attend the class, along with one other adult. So, some people would have to be content to allow their child to go without them.
I HOPE there really are individual enrollment classes in May. We'd love to go then. However, I've talked to many CMs who spoke as if they knew what they were talking about, when I knew for certain they were wrong.
