I'm curious what sort of changes they'll make, if any. My wife and I were there this past summer. It's very close to the my old office, so I'm sure we'll be there again in the future. I have family in Tucson and tend to go at least once a year.
We've only stayed at a few KOAs in the past and didn't use their amenities, so the Keep On Adding thing is something that didn't effect us. So far, none of our experiences were negative at all. Well, the one site in Missouri was so far out of level that leveling would have raised the back tires off the ground.
