I do not have any confirmed allergies but I have a limited diet by choice because of reflux and eczema issues I'm trying to work through. Gluten/dairy/sugar free, no fried foods; little to no processed foods; no beef, pork or shellfish. Limited to wild caught alaskan fish and turkey or chicken free of hormones/antibiotics/steroids, nuts, seeds, fresh/dried fruit and vegetables.
This is all by choice so I'm not sure how accomodating the restaurants would be if, for instance I would ask for a chicken sandwich in a lettuce wrap. Should I say I have an allergy even though It's never been confirmed?
I would not claim an allergy when your diet is by choice. I would suggest you be prepared to bring your own food. Disney chefs will not be able to cook any food you bring, so you may want to book a villa or suite with a kitchen/kitchenette. Nuts, seed and dried fruit is easy to bring with you. Fresh fruit is very available in the parks and the resorts. Counter service locations have small bags of carrots and many grab and go's at the value resorts have cut celery and carrots. MK has a baked potato cart.
