Class B "sweet spot"-priced campgrounds, 2 adults

Ok we do not look for the camping with the kids either, most campgrounds have a range of prices in your case ask for the lower priced sites will be just what you need -about all KOA's have tiered rates

Almost all campground will give a weekly discount which is usually buy 6 get 7 for fee this is a 14.3% discount most membership programs at 10%

I think you will find more budget rates as you head west
