If you want to change fast pass that you established in advance, do you have to get rid of all 3 of them and take your chances or if you want to keep one can you hold on to that and try to get 2 other new ones?
In theory you can absolutely modify just the one, but timing of available FPs to switch to can make it a tricky thing. You go into your list of FPs and choose the one you want to modify. It will ask whose FP you want to modify and you select everyone you want to change. It will then give you the available options, and it will not let you choose anything that overlaps with your existing FPs.
Thank you so much!
