My husband and I are taking his parents and his grandparents on a cruise beginning September 30th. We booked back in March and were given Main dining due to two family members being on chemotherapy (can't wait until late evening to eat) while at sea. Now, his aunt (63 year old sister to the dad that is terminally ill) and her daughter have booked, but Main dining is full. They have been placed on a waiting list. Does anyone know what the chances are of getting the 2 of them into Main dining with us? What are the chances that someone in Main dining will want to move to Late dining?
