Just off of 78 You could check out Jonestown KOA (under new ownership as of this spring, making significant improvements), they have a small dog play area, and our kids enjoying playing there.
Looking for more of a resort type place - try Twin Grove Campground & Resort. This has a larger dog play area, larger pool, with slide, ampitheater and a few amusement park rides. We LOVED it there, a little more pricey, but we never left the campground the entire time we were there, kids were TIRED, our little one could barely keep her eyes open for supper.
We don't fish or ATV, so I'm not much help there.
