Is it possible to order some food by request during the dining venues that are included in the ABD trips? I am on a gluten free diet. While I can usually find something on the menus that I can eat, on the rare occasion that there isn't a GF offering, is it possible to get something made up? I noticed on the SW Splendors trip there is a Pizza Party lunch prior to an excursion. Since I would not be able to eat this, would it be possible to substitute my portion with a salad?
