Bull Shoals SP has a large campground with decent sites.  Most of the sites are level and suitable for a tent and have some privacy.  The real attraction at this SP is the lake.  From fishing to boating to cooling off in the lake, there are plenty of things to do.  The playground is large and will entertain the kids for a while.  They have a wide range of hiking trails that will suit any experience level.  I recommend the Big Bluff trail, at 1 1/2 miles it is a good workout.
