as far as close to cedar point,its hard to beat bayshore estates,just east of cedar point drive on us 6
http://www.mhdcorp.com/Campgrounds/Bayshore/default.htm i stayed there in a park model in may,and will probably be staying there in a tent during the late season.
im sure others will add their comments to this as far as how the family /group features are , as it was quite empty when i was there.or if there are others farther away that might better fit your needs.
