Maybe the Disney thing is part of her feeling that she can't spend money? That she has given up things for the good of the family, even if she wanted to do things. So, maybe she likes the idea more than the park? Or even, she likes the park but never felt comfortable spending the money to go?
At any rate, good for you opening a dialogue! I think there's stuff to work with from her responses!
