Thanks. I tried to find an official BSA position on this, but quickly got confused. It seems that the BSA does not officially approve Cub Scout (at least below Weblo) camping, but our pack sent all its cubs to a council-organized campout last fall, and they're encouraging the cubs to attend a council-organized summer camp this summer. Parents are required to attend.
The problem is that the dates of the camp are very inconvenient (a 3-day camp right in the middle of the work week instead of a long weekend) and the cost is high ($200 for a son/parent to register). We can do a 1-night campout ourselves at a fraction of the cost with plenty of activities and the boys will probably have more fun.
Good point also on the uniforms. We'll make those optional, just like all the activities. Just a purely optional, unofficial, family campout.
