Have you considered Table Rock State Park? The park has a number of full hookups and there is a laundry there too. The full hookup sites in campground two are relatively new and IMO nicer than the full hookup sites in Campground one.
Here's a picture of a full hookup site we had in campground two. It was taken a couple of years ago when we still owned our Wildcat.
IMO the two best privately owned campgrounds in the Branson area are ABC and Compton Ridge. With your family Compton Ridge would probably be the best choice. I drove through Acorn Acres a few years back and was totally unimpressed.
