Best Bet is go to a website like this site Finance and look up their investment information, usually they will have contact information for corporate which would allow you to contact them and ask them directly. Given it is Disney, as soon as you say what you would like to use they will send it off to their developers to have it made. Your best bet would be to design the model, and then copyright the idea, then bring it to Disney so if they come out with your idea six months down the road you know where they got it from and you have the proof. As long as you are sitting on your idea its always possible they could develop a version on their own so you want to keep that in mind as you are planning on contacting them.
