I will offer a different take -- hope it does not offend anyone.
Our whole family flew back to Duke for about 10 days for the basketball camp and also to tour the area. It was my first time back after graduation and my wife and son had never seen Duke before. We stayed at the Inn, lingered in the Museum, strolled the Garden, gazed at the Chapel, ran in the Forest and so forth (also inspected the Franklin). That was fun.
But the basketball aspect was rather mixed. It was great to be back in CIS, see/hear K and meet players. But, two big complaints: 1) Too many kids for the number of courts available. So the kids only got about two 10-15 minute scrimmages per half day. Most of time they were sitting, watching the paint dry. 2) The player quality was uneven but overall unimpressive. (The second issue was beyond the program's control so not their fault.)
My son plays AAU basketball but he is certainly no D1 material. He gained nothing basketball skill wise at the camp. So if your child is at the level of easily making an average suburban HS varsity team down the road, then he is too advanced for the camp and would be better served by playing in a summer league with a good AAU program, if your main goal is get him better in basketball.
