Here is what you should be seeing:
Log into
MDE on a computer
In the drop down menu under My Disney Experience, You see "Plan and Manage" and "My Account".
Under "My Account" is the listing "Annual Passholders". Click on this.
This will bring you to "Home for Passholders". You should see: "Make the Most of Your Annual Pass", "Passholder Resort Special Offers", Mickey's Not So Scary Halloween Party" and "Mickey's Very Merry Christmas Party".
Click on "Passholder Resort Special Offers". This will bring up ALL offers, not just AP discounts but all GP discounts as well.
If you are not able to log into this page, your AP is not linked correctly to your MDE account. Make sure it is your AP number and not the voucher for the AP.
