We've signed up DS for the last few years. It is decent. It seems reasonably well run. Its pretty basic, its not an AMAZING camp experience, but it seems like safe and reliable basic day camp. The do arts and crafts, they play outside, they go swimming a few times a month.
My son does not love it, he thinks it is boring -- but he would like to sit at home and play Xbox instead. But when my goal is child care and keep hm busy in appropriate activities, it works.
