We recently spent 4 nights at the Hidden Valey RV Resort in Milton, WI, which is just south of Madison. We also did an easy day trip into Milwaukee, as well as a trip to see Taliesin in Spring Green (which was our main "destination for this leg of the trip).
Our site backed to a corn filed, but it was a nice spot, with plenty of room between sites, as well as open which we prefer so we can get a satellite shot. Other sites are more wooded if you prefer that.
Very clean park, nice pool. Part of the park includes park models, but they are in their own area and much better kept than we have seen elsewhere.
Seems to attract a big weekend crowd with kids, given the nice pool and other activities.
Worth checking out, we would stay there again........
