The companies that honor their quoted price do so, at least in part, to keep their good name. They want your repeat business and they want you to spread the word that they are a good company. Disney may not feel this is necessary in these situations because they have built a very large empire already, and so the money they would lose by honoring misquotes may be more than if they lose one customer's repeat business. And I'm probably correct in assuming that you yourself is still going to go to Disney.
The person that mentioned 'consideration' in an earlier post is correct. Although you may feel you made an oral contract, it doesn't appear that you actually did as you gave no consideration in the exchange. On top of this point, Disney seems to have countless protections that give them the right to change prices even after you've paid!
Sorry, although many companies would give you something for free in such a situation, Disney just isn't one of them. Honestly, that sort of practice would probably just raise prices for the rest of us.
