We just got home from 3 days in the Dells. We stayed at Bonanza for the first time. Previous stays have been at the KOA. We liked Bonanza. We stayed in the full hook up pull through sites. They include 4 wristbands for Chula Vista water park which is about a 4-5 mile drive. They are, however, literally right across the street from Mt. Olympus. You would never know it once you are in the campground. It sits in the woods nicely insulated from the beehive of activity just down the drive way. We drove by the Mt. Olympus campground (which is quite a distance away) and it looked just like previous posters have stated. It was simply a parking lot with RVs lined up next to each other.
