With the ages of your boys.... I would whole-hearteldly recommend the Great Smoky Jellystone! IMHO, it is hands down the best campground for families.
They have planned activities for kids as well as nightly movies and hayrides, etc.
They have a really nice miniature golf course as well. They owners are the best you could ever meet.
You can drive from the campground to Pigeon Forge and bypass the traffic.
Also, we like driving to Jellystone. We bypass all of the traffic heading into Pigeon Forge.
I have a few pics of Jellystone on my webshots..
