I went to camp all summer every summer from the age of 4 until 13. (Parents had to work, you know...) Mostly it was a single day camp, supplemented with a week here and there of various overnight camps.
I loved the day camp more than anything, and it was no less than critical to my social development. I was a huge nerd in school with no friends, but somehow I was the complete opposite at camp, popular and social. Sometimes a different environment is all a kid needs. Anyway, I lived for my summers.
And the overnight camps were great too; I was probably the only kid who never got homesick. I was always telling the other kids things like, "What's the big deal? I mean, you'll see them in a week..." Maybe I have an attachment disorder.
None of mine were specialized for one activity though, they were just canoeing and horseback riding and swimming and stuff. But anyway, I think if she's asking to go, she's ready. I always liked the food at my camps... but watch out for sneaking in food, it will attract animals.
