I think there is a stay limit at those campgrounds so if you want to be there for the entire Spring season, you will have to stay at one of the many parks in the area or move during your stay. We went a couple of years ago and attended all the Cubs games. Most of the private parks in the area are gravel or concrete with little or no grass but did have vegetation in the campgrounds. The one we stayed at in Apache Junction did not even allow dog walking in the park. People had to take their dogs outside the park to take care of business.
