So... are you looking for a gorgeous "resort" that you can enjoy the amenities of without leaving it, or are you looking for a really nice campground in an area that is beautiful for touring? Of course, I know everyone wants both, but wondering if you have a preference.
I have not been to a top-of-the line RV resort, but the nicest resort/campground we've been to is Fort Wilderness in Disney World, Florida. The campground itself is great, and really not a ton of kids around because there is simply so much to do in Disney World. Wife and I are semi-planning a trip there in a few years, just us without the kids.
At the other end of the East Coast is Acadia National Park in Maine. The national park campgrounds are gorgeous, but no hookups and are really tight for getting big rigs in (I would call them not big rig accessible). I don't know the other private campgrounds in the Bar Harbor area or just outside it, but a couple are highly rated. Acadia is just gorgeous for exploring... and the way it is laid out, you can choose to do the energetic hiking thing, bicycling on the carriage roads, or drive a car to most of the lookout areas. It is really neat to go to the top of Cadillac Mountain to see the sunrise- each day, you can be the first people on the continental United States to see it.
Have fun next summer!
