We are a large group and have the Disney Dining plan. We are trying to figure out when it begins and ends. For example, we arrive at our hotel in late afternoon so does our dining plan start when we check in or at the beginning of that day? We are trying to figure out if we need to book a table service dinner for that day as our plan has 1 per day or if we have a table service, quick service and 2 snacks for what really is just a partial day. Same on check out day as we are checking out do we have a table service, quick service and snacks for that day too? TIA.
