Yes, it is these kinds of people with REAL issues.... innkeepers NEED to know about in advance. And if that severe, most travel with their own food like you said because they don't want to take any chances.A little late to the game, but just an FYI. Many people who can't eat "gluten" have celiac. My SIL has that, and although she's tall and thin, if she breaks the diet her stomach swells and she looks 8 months pregnant - very painful. She can rarely eat 'safely' without running an inquiry with the cook. For example, it's not only wheat, but nitrates (bacon), most cheeses, some icing sugar (!), etc. That being said, she's a reasonable person and when she travels she brings her own food!!!.
