Can I call up and add a day to my current ressie or will they have to book a new ressie. I want to add a day and add an extra dining day but I don't really need an extra park ticket. Can I just add a night and dining? If I have to make a new ressie will they apply my old payments? It will cost a lot more money if I have to add a ressie becuase I will have to add 1 day tickets. Right now we have 8 nights and 9 day park hoppers. I want 9 nights and 9 day park hoppers since we are arriving really late.
