So...apparently I just need to be a bit more patient! Expedia.ca sent me another email this morning with the information I needed! For anyone else who gets tickets through them and can't link them when you get the voucher, the email you need contains this info:
Step 1
Register or Sign in to StartYourDisneyExperience.com
This will take you to the
My Disney Experience website. Set up additional party members in the ‘Family and Friends’ section.
Step 2
Link Your Walt Disney World Ticket
Once you’re signed in to
StartYourDisneyExperience.com, enter your Disney Ticket Confirmation. Your confirmation number is
XXXXXXXXXXXX.
To access
Disney FastPass+ service, you’ll need to link a ticket for each member of your travel party age three (3) or older.
(
FastPass+ experiences, the number of selections Guests can make and arrival windows are limited.)
Please note: If you booked your tickets as part of a vacation package on Expedia for a select Walt Disney World Resort hotels, you received a hotel confirmation number in a separate email immediately after you booked
. Use this number to add your hotel reservation to
My Disney Experience and customize your MagicBands.
Step 3
Select your FastPass+ Experiences,
Step 4
Make Dining Reservations and Explore My Disney Experience, Including Online Check-in at Select Disney Resort Hotels
Simply choose these options from
