2. But I don't they can make them with rice dream. Even if they did they would also have to replace the milk with something else like rice milk.
3. Do you mean one made with soy or free of soy. I can't think of any ingredient in a milk shake that has soy in it. Though I'm not trying to avoid soy so I really don't know. But Disney keeps a list of everything that's in everything so they do know.
Disney are wonderful with allergies so ask about the soy free. I had a meal at 50's Prime Time and allergic to soy so the chef came out and spoke with me to make sure the food I selected was free from everything I was allergic to. (there is alot!)
