School Camps are wonderful.
The first day is a little alien, but after that it's fine...and the kids learn how to be around others, in a bigger setting, how to help others, and interact as a team.
My youngest son run's Camps for school age children, and it will always take a bit of time to adjust.I think it is part of life, and growing up.
There are so many things for them to do, and really if they were asked 'if' they would stay another week.......they would!
