I know Disney will charge your card $10 per person if you fail to show up for your reservation, but can anyone tell me if they still charge you if 3 out of 4 people show up? My mother-in-law will be joining my husband, son and I for at least part of our trip, but she in unsure how long she able to stay due to work. We had initially thought she was staying the entire time and make ADR's accordingly. Now that she may only be staying for 5 days out of the 9 do I need to re-book all these reservations as 3-person or will I be ok leaving them as 4-person. I don't want to be charged an extra $10 at every meal.
