So I was recently given a one day Magic Your Way ticket and I want to upgrade it to a FL resident 3 day ticket w/park hopper (I called WDW and confirmed this was possible.) I already know upgrades need to be done at guest services, but if I were to book my resort a few months prior, I am guessing I would only be able to select fp+ times for my 1 day ticket. Do you think once I am actually in the parks and I upgrade, I can select fp+ times just 2 days prior? Would I be stuck with terrible fp+ choices? Or would they scrap my 1 day ticket and issue me a brand new 3 day ticket, meaning I have lost all fp+ reservations for that 1 day? I have never upgraded a ticket before, so I don't know what to expect, especially now with the addition of fp+.
