Expedia WDW Park Passes [Paper Vouchers] and MDE?

[Max M]

Hi There,

We've purchased WDW Park Passes from Orbitz before, and usually within 48-72 hours, Orbitz provides a Disney Confirmation code that one can input on MDE.

We purchased our WDW Park Passes from Expedia this time, and noticed that Expedia has paper vouchers that say they are redeemable at the gate at WDW.

Since we already have MagicBands, and are staying on-property [The Dolphin], if after 72 hours I don't see a Disney Confirmation number for our park passes, should I contact Expedia for the Disney Confirmation number, or if I provide the Expedia Voucher number to a Disney CM over the phone, would that be the best way to get the Disney confirmation number? Or will we have to wait to redeem them in person at one of the Guest Service desks at The Parks, or with an Official Disney Guest Services employee [during the hours they're stationed at the Dolphin/Swan properties]?

I'd love to be able to do this so that we are able to get FastPass+ established for rides/attractions we want to go on during our stay at WDW.

Thanks in Advance!
