Hi Palau,
How exciting that you will be spending Christmas at the Happiest Place on Earth!!! I understand being away from the family during the holidays can be hard but this will be a very magical Christmas for your family!!
Anywhere you choose to eat will be fabulous. For that extra bit of magic and with you having two princesses, I would choose
Cinderella's Royal Table. Dining with princesses at Christmas would be an incredible experience and leave a lasting memory. Here are some other fun choices:
1900 Park Fare,
Chef Mickey's,
Crystal Palace. My kids love character dining and so do I!
Reservations fill up quickly during the holidays, so make sure you book as soon as possible.
407 WDW DINE
Make sure you pick up an autograph book to take with you to any character dining restaurant!
Thank you for your question, if you have any other questions, please let me know.
Wishing you and your family a magical vacation!
Carrie
