Hi Andrew!
Thank you for visiting the Moms Panel!
The Magic Kingdom park is the one park that is likely to reach full capacity on Christmas Day, so if you wish to avoid the biggest crowds,
Animal Kingdom is a great choice, and your children are sure to enjoy themselves.
As you enter the park, be sure to pick up a copy of the Times Guide for the
entertainment schedule for the day, and details of all the character 'meet & greets' throughout the park.
If you have any other questions, please come back and ask me - I would be happy to help you plan you magical vacation!
