Hi Sarah and thank you so much for the compliment,
I wish I could wave my magic wand and give you an answer but unfortunately, we are non the wiser.
The online dining reservation system currently only allows guests to make advanced dining reservations for the
Hoop-Dee-Doo Musical Revue for dates up to and including 16 October 2011 and displays the following note on it's 'Make A Reservation' page:-
"Please note, the Hoop-Dee-Doo Musical Revue can be booked through
October 16,
2011, pending availability. If you are arriving after that date and
would like to make a reservation, please try again later or continue to
explore
Disneyworld.com/dine for alternative dining options."
My best advice would be to keep checking the Walt Disney World website and calling (407) WDW-DINE or (407) 939-3463 for more information.
Wishing you a magical trip!
