Even the wikipedia definition is lacking with generalities. As a kid, I went to 4-H camp. We slept on wooden platforms in tents, the "dining hall" was a cement slab with a roof, we did standard camping fair: hiking, campfires, nature walks, etc. We did have a swimming pool (after they had to drain the swimming hole in the creek when a camper went missing, they built it). We did have electricity in select spots (dining hall, girls and boys camps, restrooms, and campfire round). So some "kids summer camps" do fit the idea of camping.
