If seeing some sights is important, I would recommend going to Table Rock, then head north to Springfield to see BPS World HeadQuarters, NRA Museum in BPS, Wonders of Wildlife, and Lews HQ and Sportsmans. You would also be close to Branson, with plenty of other family options. Table Rock has great largemouth, smallmouth and Kentucky fishing. In July, the fish will be DEEP.
Beaver is best known for Striper fishing but also has good bass fishing.
I would also spend a couple of days on Bull Shoals, excellent bass fishing lake.
