There are a number of COE campgrounds around Table Rock Lake. Most are pretty nice but don't have swimming pools etc. Our favorite is Old Highway 86 Campground near Ridgedale, MO, about 20-30 minutes south of Branson.
If wanting to fish for trout, I'd recommend Cooper Creek, off Fall Creek Road on the banks of Lake Taneycomo.

Make sure you go to Titanic. I think you need to make a reservation but it's worth the effort.
