My husband and I are interested in purchasing the Meal Deal and Sipper Cup for us and our 2 kids. We know that you have to purchase a meal ticket for each person and each day. Our question is, do you have to purchase a different sipper cup each day, our can you use the same one for each day that you have a meal ticket? If you have to purchase one for each day, can you share your drink (i.e., we buy 2 cups, my daughter & I share one, and my husband & son share one)? It seems like a great deal, I just don't want to have to bring home 16!!! sipper cups LOL!!!
