I was in Disney World this summer and found that they are pretty good with the vegetarian options. The Sci-Fi Dine In Theater (in Hollywood Studios) has an awesome Seared Tofu with mango glaze, and there were veggie burgers available at the counter service type places. Overall, I think everywhere we ate, both in the parks and hotels, had a vegetarian choice. And not just a portabella mushroom!! (I appreciate the effort of the stores that do that, but I hate mushrooms!)
So, just wanted to share the good news. It's probably not news, but I was pleasantly surprised.
