DD5 is allergic to peanuts and tree nuts and they were super accomodating. I know a girl who has very serious allergies and they were even able to make it safe for her to eat. I recall 'Ohana actually made her all sorts of special foods for every course of the meal.
I would highly recommend you email WDW at
specialdiets@disneyworld.com. I have a huge email from them about how they handle allergies and intollerances, but it won't let me paste it on here. I do know there is a special form you'll need to complete if you fit any of the following criteria...
- PKU
- Metabolic disorders
- A single guest with 4 or more allergies/intolerances
If you fit any of the above 3 scenarios, ithe form they have you complete will list out all of your adrs and they'll get with the various chefs in advance to make safe food for you.
I've read soooooo many positive Disney dining stories on our allergy forum, so I'm sure they can work with you. I've even heard CS spots bending over backwards to accomodate allergies.
