It's demanding work to teach for hours on end and part of their enthusiasm which should be passed on to the kids. Be sure you have planned for support staff as well. People who record free throw and shooting game results, register campers, get insurance and permission slips in on time, can chase down details for you as the camp director as problems occur during the week, and even man a snack bar or drinks area during the camp. The most important person for you will probably be the facilities manager because without their help you'll have problems getting the right equipment up and down and resolving technical problems such as baskets jamming, someone to collect and lock balls, and fix broken toilets, for example. Smooth facility operations contribute to successful camps.
Kids love to watch high level highlight videos or humorous one's to lift their mood from tired legs.
Make your camp fun. I like my camps to have not only an instructional theme but also a social theme. Kids know when you invest love in them. If you run camps over a number of years the kids will pick up on this and mail will arrive from many unknown but wonderfully funny places. All of these things contribute to the joy of a young campers experience.
