We are a large, extended (4 generations) party of 17 doing Disney in June. We had previously (at the 6 months out mark) been a party of 16 and we recently added Great Grandma. I have 2 dining reservations for 16 ppl, breakfast at Cinerella’s Royal Table and a dinner at the California Grill. I am having a hard time trying to modify the reservations to 17ppl, i have called several times. The youngest in our party will be 5 months old. Do we really need a reservation for him? Or, do you think we can just show up with 17 and pretend we didn’t think he needed one?
