We have are ADRs all set for next month and now my mother in law is going to come over to see the girls for a few days.... Is it possible to show up for our reservation and add another person? We have reservations for 6 (2 adults, 9, 8, 5, & 3 year olds) now and need to add one more adult... I called and Disney told me they could not add a person I had to make completely new reservations.... The restaurants in question are Chef Mickeys, Coral Reef, Tusker House Breakfast, and Cape May Breakfast if that matters... Thanks!
