My plan for years has been 1st alternate Appleton, 2nd Madison, 3rd Stay somewhere south of the front and wait it out. And there is almost always a front of some kind that week.
With the new arrivals plan, Madison is a good place to stop anyway, to grab breakfast or coffee and get your head together on what comes next.
Note that Appleton won't have camping this year: "Aircraft will be allowed to park at ATW for Air Venture 2023. However, we will not have camping this year."
