I'm hoping you guys can help me, as seasoned HDD goers.
I have a large reservation for June - 20 adults, 1 child (3), and 1 infant. One of the couples has now said they'd like to bring their daughter (9). I just rang Disney Dining to add her on, but they're saying I need to drop to category 2. She's only small, and we're all family, so how pissed would HDD get if we showed up on the night and asked for an extra chair? I will obviously pay for her there and then. (I'll also keep trying the dining line in case availability show up).
