Called this morning at 9:40 am and was able to get a reservation for 3 people for August 4th. They didn't ask for my reservation number, only my DVC member number. Since it was a disney dining person I was talking to, and probably not someone looking at my existing reservations, makes me wonder if any DVC member could sign up for the event, regardless of whether or not they have a reservation for that night. Calling at 9:40 I had 0 wait, and got directly connected to a cast member. I am totally excited for this event. I'm cautiously optimistic that my 5 year old will be able to handle the late night.
Interesting... I only gave my reservation number and not my DVC member number. I forgot all about it this morning and didn't call until lunch time! I didn't realize we can get in early. I made ADR's for 7:30 thinking we'd go over after dinner for the party to start. (we have a car) Now I'm not sure.
