Hello Tony!
Welcome to the Disney Parks Moms Panel with a great question!
Be Our Guest Restaurant is one of the most popular restaurants at the Walt Disney World Resort at the moment, which means reservations are sometimes hard to get. Dinner will soon start offering a unique dining experience with a 3-course menu, so I also cannot wait to make reservations there for my family’s visit in December. If you were not able to find an available table for December 3, I highly recommend that you keep trying. Since reservations can be made 180 days in advance, until the end of the year many things can happen and Guests end up changing their plans.
However, if this is a very important experience for your granddaughter, then I have a great suggestion! During your visit one of the most beloved special events of the season will be offered:
Mickey’s Very Merry Christmas Party. This is the best way to celebrate the spirit of the holidays, and you are also able to
make dining reservations at participating restaurants that will be open during the event. The party takes place on select nights, and when I checked I was able to find tables for dinner at Be Our Guest on December 2, 4, 6, and 7. Please note that a separate ticket is required for the party. You will absolutely love it! The snow on Main Street U.S.A., the amazing treats, special parades and shows, and character meet and greet experiences are simply unforgettable.
I hope this helps you while planning, Tony! It was a pleasure answering you question, and I hope that you stop by once again real soon!
Best magical wishes,
Thiana
