Can't say I have ever stayed at any RV park that I would rate 5 stars. Not that I stay in low class places, just none that I would rate that high. And if I did find one like that, I probably would not pay the price to stay there.
Having said that, we stayed at the KOA just off the main strip in Branson and will stay there again. They have several levels of sites ranging from small back-ins to large pull thrus with patio, outdoor furniture, and fireplaces with prices rising accordingly. Convenient to most shows on the strip and near the yellow route to bypass traffic on the strip.
