We also have a large practice green that gets severely abused throughout the season by camps,events, group lessons etc.. We keep a set of bayonette tines on our aercore 800 and will aerate weekly. We also core aerate with 3/8" tines montly and just keep the holes open. Since it's a practice green we can get away with pretty much whatever we want because nobody actually pays to use it. Since you've got two greens, maybe raise the height all the way up to 1/4" on the green that the kids will use. They certainly won't notice.
