We are undecided about getting the DDP or the Deluxe Plan. We will be staying for 2 nights. We will get there around noon the first day, park day the second, and be there for breakfast the last day. If we get the deluxe i know I can use a CS meal in place of a TS right? What about snacks. If we have an extra TS meal, can we get a snack in place of it? Just to use it up?
