We are going in April and have the Dinning Plus Plan. How does that work when ordering meals? For example, at counter service, do I have to order the meal, drink, and desert all at the same time? At the sit-down, if dinner fills us and we don't order desert, do we forfeit the desert? Or can we go someplace else later on for the desert? If we can split up the orders, how does that work - does our card just figure it out?
