We stayed 5 nights in Acorn campground at site AC009.  The sites are offset a bit, so even with side by side neighbors you felt like you had your own space.  There is water and electrical where we were.  Not far out of this campground was a dual dump site.  There is plenty to do from hiking trails to renting canoes, biking and swimming.  We have previously stayed in their cabins which was a memorable time for our entire family.    With Verizon as our provider, we had no service in Acorn campground.  Minimal service was available on higher ground.  Great museum and nature centers.  In the Acorn area there were showers and flushing toilets.  With all there is to do, best give yourself time to explore the area.
