My friend invited me to Six Flags last year. I had diabetes, but not celiac disease, so I am concerned more about it. They usually have dinner in the park, but you bring your own lunch to eat outside the park. So I am ok for lunch but not dinner. I will not be too much of a dispute over this. They do not allow food inside the park. So, what should I do? By the way, I can not eat what on the inside, if they contain gluten. Just to be on the safe side.
