Hello friend. I travel 2x a year to the World and I have a severe allergy to dairy. Here are some of the success stories from my last trip:
Ohana Breakfast , the chef went out of her way to make sure I had the exact same breakfast my family had (minus the sweet bread and butter) with waffles included. She came out twice to see if I would like anything else, which I thought was very kind.
Liberty Tree Tavern made me my ONLY serving the whole trip of mashed potatoes AND gravy. He said to me he had Toffuti Ice Cream and I said "Ooooh with Root Beer I could make a float", he was nice enough to make me my own delicious ICE COLD FLOAT in a to go cup!
Carlos, the manager at Captain Cooks ALWAYS made sure when he saw me or my husband come in that he rushed around the counter to take the order. He found the Tapioca bread when NO ONE else could and was a true gentleman.
Chef TJ and 1900 Park Fare walked the whole entire buffet with me and if I saw something I liked that I couldnt have, he came out with a dairy free version for me. He made me some special rice, he steamed a delicious Red Bliss potato for me, made me special salad with Oil and Vinegar and made me a desert that was 1/2 a pineapple, marshmallows, fruit, dairy free brownies in a dairy free dark chocolate sauce.
Good Points: You can find lots of Dairy/Gluten Free dessert choices at the counter services like Enjoy Life Cookies. Lots of the counter services were truly accomidating and more knowdlegeable than the Chef as far as what they were capable in offering me dairy free wise. The Manager at Restaurantosaurus was great at knowing exactly what was needed to modify a salad for me, as opposed to the Chef at Kona Cafe who kept giving me "Well, its made with butter, but not that much."
Places like Chef Mickey, honestly I would rather eat my shoe then the nasty nasty dairy cupcake they offered.
Make sure you go to DTD to Babycakes and get her some sweets for the room!
At the Ice Cream shop on Main Street they have a dairy free ice cream so she can even get an ice cream cone! What a treat!
I even did the Wishes Dessert Party where they offered me a huge platter of delicious dairy free/vegan treats! One of the best things I have done Dairy Free in Disney!
Make sure all your dining resides have it marked "Allergy" on the ticket. It will delay the bread and butter coming to your table, but it is well worth it for the safety aspect.
As far as the dairy free waffle, yes they will be able to accommodate that or eggs. The dairy free bread is sparse I found, for say toast in the am. Yes, they will be able to get your child a soy milk box, it's a crappy brand Kikoman (in Oct).
Please feel free to inbox me with your dining ideas or ressies as I can certainly help, and would love to help you, I have eaten at most places.
