Hi All,
I just returned from WDW on November 20th - so I have some answers to the Canadian Discounted tickets.
I personally purchased the tickets via WDW website. The tickets were automatically linked to my
MDE account and I was able to make FastPass selection right away since I was staying on site and it was less than 60 days out.
I was able to upgrade the tickets to an annual pass. This was done at the ticket booth at the International Gateway at Epcot. When I showed the print out (voucher), passport and credit card that used to initially purchase the ticket - the cast member did not seem too concern??? She was going to give me a separate admission ticket (the plastic card) but then I showed her that I had magic band that was nixed. Upgrading to the annual pass was easy - but they did not bridged the price.
If there is anything else I can answer - please ask away!
