That's because adults are responding. My kids love state parks, but they also love rv parks with a passion. My daughter's absolute favorite campground is a yogi bear in Indiana that has 3 pools and water slides, golf carts, etc. It's ridiculously packed with people and activities.
My boys' favorite is a KOA in Michigan with pools, bumper boats, and go cart track. It costs $40/kid/day to go cart. Lakes at state parks are free. Parents usually prefer free. ;-)

Most Core of Engineer campgrounds are very nice. Located primarily in the SE, all on bodies of water. Usually a wide variety of sites, good separation, and many have E and W hookups. Easily the best bargain with a Senior National Park Pass for 1/2 price camping.

Fort Wilderness Campground at Disney was pretty amazing. Wish I could have spent more time there, but after a day at Disney, in June, you just either want to stick your face in the AC or float in a pool.
