First I did an online chat, was told I was good to go. To verify, I did a follow up call to ticketing, and was told the opposite, then I sent an email, which led to DVC calling while I was driving yesterday, with a sympathetic DVC rep, who said the system shows it would be cancelled, to be fair to the DVC Rep, she fully understood the problem and seemed genuinely surprised at who it could effect guests, she said she made several notes in the system and noted the communication in my profile, and she referred me back to ticketing. I called ticketing when I got home and I was told I'd ne fine. I really hope someone responds via email, so I have something in writing, which Disney seems very adverse to do (I wonder why). I did write down the name of the ticketing rep, the date and time of the call. I think over the last few days they may have realized that there may be several hundred, maybe thousands, of guests that have planned their trip, who don't regularly check Disney boards and videos, that would simply show up Thanksgiving week expecting that their vacation is secure.
Imagine the fun the local news media and perhaps National media could have with that! "Meet Jane Doe from a small town in mid-America, who saved up for two years for a Disney trip, she gets to Florida with her family and Disney tells her "No!" Cut to video of crying kids in mouse ears that want to see Mickey Mouse. Now imagine that multiplied hundreds or even thousands of times.
Also I've taken screenshots of the gold pass blockout dates, the Sorcerer Pass blockout dates, my ticket showing in
MDE, and my "plans" in MDE showing I have park dates reserved. I did this in case the system automatically make the ticket type and dates in your MDE account quietly change on September 8 when the new APs come online.
I honestly think these changes were rushed through without much thought other than something fresh, new, and more expensive for the 50th anniversary.
