We aren't going to Disney until May 2022. We will purchase our tix from a third party vendor. Should we wait until Genie is instituted or can it be added later?
Add it later if you want. If it's not a busy time you may not even need it. I never bought maxx pass at Disneyland and went on all the rides I wanted to. However, Disneyland still offered free paper fast passes at the time. I am going to wdw in the fall and hope genie is still in the bottle. If not, I will just adjust my ride strategy. I won't be adding to an already expensive ticket.
