We are in Branson once or twice every year offer the following suggestions.
Use the alternate routes that parallel 76 hiway and the traffic is manageable.
The KOA is a good CG and close to many attractions, we like Musicland but may be limited on pull thrus.
Best places to eat: the Keeter Center at the College of the Ozarks, the Bradford Inn (lunch only), numerous restaurants in the "Landing " at old town Branson.
Recommended shows: The Million Dollar Quartet, the Hughes Brothers , the Haywood's and the Duttons.
Plan to spend some time at "Top of the Rock" and eat at one of the restaurants. Located about five miles south of Branson just west of Hwy 65. The entrance fee is deducted from restaurant or gift shop charges , it's worth the experience.
