Hi Daniela! Walt Disney World works very hard to accommodate guests with allergies. The chefs in the table-service restaurants can prepare a special meal for your daughter free of milk, eggs, wheat and peanuts, and each park has quick-service locations that carry gluten-free and nut-free products. Click
HERE to see a list of those locations, as well as additional information on special diets at Disney.
I recommend that you contact the Special Diet department at Disney at least two weeks before your trip. You can reach them at 407-824-5967 or by emailing
SpecialDiets@DisneyWorld.com. Also, when you make your dining reservations, make sure you have the castmember note your daughter's allergies on the reservation.
Hope you have a wonderful time!
