I want to make sure that this nonsense is correct. I have a tier 2 one day ticket. I want to make a reservation for a tier 4 day. The ONLY way I can do this is by going to a guest relations location and paying the additional cost in person. All of the guest relations locations listed on the Disney website are inside the parks. So, in order to upgrade my ticket I have to buy another ticket?
