In that case, I know that the Marketplace sells eggs, butter, milk, etc.; they also sell Mickey measuring cups and measuring spoons, and other cooking utensils (of course, overpriced, but cute). I do not recall seeing baking pans, though. I would think you could bring disposable aluminum pans...lightweight and throwaway. The Boardwalk's Screen Door General Store also carries groceries.I hadn't thought of baking before, but I don't think it will work. We arrive on the 13th and her birthday isn't until the 21st.
I would think that you would be able to call and find out if they have what you will need. You have a lucky daughter!
