So .. I did try and call the AP line today to see if they would let me get APs for the rest of my family (since I already have one). I didn't press it, but they said .. no .. I'd just have to buy regular tickets for the rest of my family. But, as stated above, if you do buy tickets for a future trip they will be happy to upgrade those to an AP when they do start selling them. Which I don't think is anything special, I think they always would let you upgrade your tickets to an AP.
Didn't hurt to try, and frankly I am just not sure if I'd want to commit to January 2021-January 2022 right now. If anything I'd just want to get APs and hang onto them for the far future before the prices inevitably go up. But hey .. who knows .. maybe Disney will be desperate and lower season pass prices to entice guests to come often? *lol* .. I know .. who am I kidding?
It's probably more economical to just use the one AP for the discounts at this point -- I don't see myself going three times in 2021 the way things are going.
