I have vouchers for my WDW theme park tickets from Expedia and Travelocity, and I cannot link them to MDE. I understand that I need some type of Disney specific number rather than my itinerary number from my vouchers, but I have been unable to get that number from Expedia or Travelocity. Can anyone help me get what I need? Maybe I'm just asking for the wrong thing or I need to call a different department, but this is beyond frustrating.
