This is an excellent blog posting with an excellent community response, and quite encouraging: The AllergyEats Blog » Dining at Disney with food allergies – a follow-up.  (You may want to read this blog first.)

I’m going to have to plan ahead and look at the meal plans when we finally decide to go to Disney.  It’s great news that chefs will come out & prepare food in front of you, it would be entertaining as well as putting you fully at ease.
