There is a major disconnect in what your DD wants to do and
where the jobs are.
I get that your DD is artistic. I am a professional artist. No one on this thread is trying to talk your DD out of becoming a Disney animator, but you both seem to have a misunderstanding on WHERE Disney is hiring animators and where they will actually be working. That's in Burbank, CA, at the animation facility, not at a Disney
theme park. Any of the Disney theme parks. Theme park jobs are customer service, hospitality or entertainment, and technical back of the house, operational jobs. Unless she just wants a technical job to operate the equipment that turns on & off the animations and thinks that's enough to get her noticed in Burbank?
The animations are done long, long before they get to a theme park. The ideas for development have to get worked on, tested & approved, go through the legal & copyright requirements, make sure they follow Disney guidelines, etc., and fit what Disney wants at their theme parks, in Burbank, CA. Pixar Animation Studio, (a subsidiary of Disney,) is also located in L.A.
DD can make all her own animation she wants while working at WDW,
Disneyland Paris, Hong Kong Disney, even at DL in Anaheim. She can even show them off to fellow theme park co-workers & managers. But, none of that will get her recognized and working with the animation team at the Burbank studio. The theme park resume credit won't even count towards working in Animation. They are very separate fields and career requirements.
If Disney animation is really your goal, you both need to research what is really required, and where that needs to be to get her there. Just like, if she wanted to do Broadway, she can't do dinner theatre in Utah and think her work there will get noticed, or that those credits will really make her competitive on Broadway. If she wanted to work in Information Technology, she needs to be in Silicon Valley, CA.
Perhaps moving to California is a wiser move. It's still down south, better weather. An opportunity for DD to be working at DL, AND when she finds out the Disney animation jobs are in Burbank, it's only a 2.5 hour commute from Anaheim. If you and your family live somewhere in between those two locations, the change in locations will be much less complicated for DD and she can still live at home.
