I brought my son when he was 12 or 13. We set him up in his own tent and he was able to find others his age without problem. While he didn't do it, I know of lots of kids in that range who volunteered in the non-movement area of Vintage (various red barn things like selling pop corn, helping with the plaques and stuff, working on the Vintage daily news letter). He just took some cash from us in the morning and we didn't see him again until dinner.
