Neat resource! I'd suggest double checking on arrival, as it's always possible recipes may have changed. I've always been really pleased with how Disney handles allergies and intolerances; if you have an unusual one they might not have flagged as a common allergen, they should be able to provide you a binder with ingredients so you can check for yourself. Source: I have corn intolerance, which no one ever flags for. Super helpful CMs all around when I ask for ingredient lists and alterations.
DS has a peanut allergy. We told our server who brought us a menu specifically designed to assist folks with allergies, went over ingredients with us and I believe noted in somehow in his profile on MDE because after that we were always asked if we needed the special menu.
