This all still comes back to how big of a stink you are personally comfortable making.
It seems the way the paperwork was complete and submitted to Disney has tied Disney's hands.
You now have two choices:
a. sit back and wait,
b. Force Disney's hand,
Disney is going on the paperwork the was presented to them, phone calls are all well and good but don't actually do much. Presenting Disney's the proper paperwork to stake you claim will untie their hands and allow them to fix this for you.
However, it will also force them to cancel the standing reservation.
The contract just say there are not point available until 2024, it make not reference to a pending vacation because they would have had to delayed closing. Someone wanted this deal closed for whatever reason. They did not follow the proper procedure. They may have broken the law.
This is a real estate transaction plain and simple, you bought a house and the former owner hasn't moved out. If you want to let them stay, then you have to wait until they are done to book you next vacation. If you want to use your membership well you need to stand up for yourself and have them removed.
The seller's legal beef is going to be between him and the broker. He can't go into court and say I transferred the deed but I still wanted to use the property.
Well, I mean this is America (s)he can do that, but it will not be very productive.
Here is the title change form.

Include a copy of the controller website showing the transfer of deed,
Include a letter stating.
This deed was transfer on ...... For what ever reason the membership was not transferred into may name. I have made numerous calls to the broker, title company and member administration. Someone has lied to me.
I now formally demand you transfer the membership to me account, so that I may use my membership.
Good luck with whatever course of action you take.
