I think that it could be a good experience, but, saying that, it's not for every child. If he's pretty outgoing and isn't afraid of being away from home that's one thing, but if he's on the shy side and hasn't been away before, it could be hard for him. The worst thing might be to be somewhere else where he doesn't know anyone and is homesick. That would not be a good thing.
However, if you talk to him about all the positives and negatives of camp and still wants to go, then it would be worthwhile. From what I've heard from other people, there's a lot of postive things to going too.
Yes, he'll learn or review Diabetes management, he'll be able to talk with other kids about this disease (and may not feel as alone), and he'll also do all the usual fun camp things... (camp fires and smores come to mind

).
I wish you luck with your decision...keep us posted
