The fact is, we don't have the AP data. I'd bet it's not at a cost to Disney at all. We need to know how many times people use their passes, how many times they go the whole day and try to ride all the rides, etc. Unless the parks hit capacity, APs aren't impacting a normal guest outside of wait times, and we need a lot more data to know how much of an issue even that is. I know when I had them back in the day, I lived in St. Pete, so it was much more about taking a few trips for the parks, and then the rest of the time random day trips (maybe I'm going to HoB for a concert, so I head to Epcot to eat some Fish and Chips beforehand, etc.).
