The really hard part is finding the park that meets your RVing style and gleaning that info from the reviews and recommendations. For example, we don't camp, we travel to see the sights. We want concrete patios, wide spaces and large level driveways for the coach. We appreciate landscaping and a neighborhood feel. We love campgrounds like The Portal in Moab (resort side), Yellowstone Grizzly and the Las Vegas Motor Coach Resort. We were very unhappy with Ruby's Inn at Bryce Canyon, Mountain Shadows in Salt Lake City that many people just love. There is no right, no "best campground" that meets all RVing styles needs. The reviews are very helpful, but we always look for key words and specifics and never book any space without looking at the google view.
