Leaving to see Mickey in three weeks. Since my last trip, I've been diagnosed with diabetes and it's now severe..to the point where I'm about to be put on insulin. I can't afford to mess up and am so worried about what I'm going to eat at all these great restaurants! To make matters worse, I am now on a gluten free diet. Can you get gluten free foods/entries at Disney? Do I need to let them know ahead of time? Or can you just mention it when you get to the restaurant?
