DisneyGrampa has good advice - disABILITIES have been great at helping out with my gluten free questions. Post your question there and put a title like "Diabetic - HELP" in the title bar to attract relevant responses easily. Also, ask someone to give you the email address for the Disney Special Diets team. They will email you a list of CS and TS places that can accommodate you (most of which can in one way or another). I can't remember the email address off the top of my head, but I don't know if there is a different one for diabetic queries so maybe just ask anyway to be sure you get to the right department.
