A weekend dilema

I am going out of town for the weekend and starting to feel the pressure. How do I maintain my commitment to this journey and be a polite guest? I am trying to be prepared by packing snacks that I have made for K and intend to bring some fruit and veggies as well. The obstacles I am not sure how to avoid are the meals that are planned for restaurants and the unexpected snacks/treats that will be offered to K.

I am struggling with the balance of how to instill this experiement in K while at the same time not forcing her to be an outsider among her peers. I am really loving the change and believe it will relax a bit after my month long experiement but not be over. If I didn't intend to keep going I would probably not worry so much about keeping k away from the temptations and just let her enjoy. This is certainly a battle I will have to choose how to fight.
