So, I had non expiring tickets that I’m using this year. I was able to load them to MDE but when I went to make park reservations i couldn’t. I had to call Disney and they had to add some kind of comp ticket to my account in order for me to be able to do it. So while in theory it SHOULD be easy, it did require quite a few hours of being on hold. Once I got the right person, it took about 15 minutes.
