Hey there Amber! Welcome to the Disney Parks Moms Panel!
Making
Advanced Dining Reservations becomes available to you 180 days before your check-in date, even if your Disney vacation package is not paid in full. If you check in date is December 29, you will be able to make dining reservations for your entire Disney vacation beginning July 2 at 7am EST.
Remember that popular dining experiences like
Cinderella's Royal Table,
Be Our Guest, and
Chef Mickey's tend to be hard to get reservations, so I would suggest to keep checking the Disney website from time to time, as guests change their plans often popular reservations become available.
Also, if you have to modify or cancel your Disney vacation, remember to change or cancel your Advanced Dining Reservations, as well.
Amber, here's to wishing you a magical holiday Disney vacation. Please visit with us again if you have questions about special events around the New Year. We're excited to help!
Happy planning,
Korliss
