Which school was it?

Last year our son struggled a bit during summer camp at his private school - which he otherwise enjoys and does well in during the fall and spring. In particular, he struggled with adapting to a new set of kids every week and the lack of structure he usually has during school in the fall and spring. We're not necessarily looking for academically-focused summer camp(s), but any recommendations for ones that have a little bit of structure and perhaps more stability for kids in the 4-5 year old age range would be much appreciated. Thanks!
