I do wonder in practice how this really works for making friends, once you leave camp there is now a distance limitation.
But I have long wondered about the idea of recreating some of the experiences from childhood as adults. Things like camp, maybe going to a "day care", or other things to just not think about all of the stress of life for a little bit.
Sure we have things like going to Disney, amusement parks, adult oriented arcades like Dave and Busters. But as fun as those are they are not really replicating the childhood experience like this seems to do and other things that could be made similar.
