we have a group of 17 going to Disney in October. Some dining reservations are for all 17 , some for just 12 of us and the other 5 are dining elsewhere. 12 are on dining plan, the other 5 are not. We have very dear friends that had traveled with us in the past but her health would no longer allow it. She passed away about a month or so ago and he is moving back near us. We would like to invite him to travel with us but are not sure about the dining part. Has anyone ever had luck adding 1 to your reservations..several years ago we did but we were going from an odd # to even.. we don’t want him to have to eat alone but I know I would never get the reservations I have again if I cancelled what I have.
