If you do not have RVParky you need to get it. It is so informative on campgrounds, state parks and all camping areas in the us.
We are at Yogi Bear park in cherokee now til Wed. April 2, then we are going to Pride resort in Waynesville. I think they take Passport and other forms of discount. We are going on Coast 2 coast. First time at both campgrounds so I can't give a review on Pride, but I don't think we will return to Yogi Bear park unless we bring the grands.
Don't forget RVParky. I have it on my phone and laptop. It is a free app.
