Hello, Mark! December is a magical time to visit the Walt Disney World Resort. Millions of festive lights, garlands and ornaments deck the walls to add an extra-special feel to the Disney Parks experience.
You do not need to purchase additional tickets to experience the theme parks at their holiday best, with the exception of
Mickey's Very Merry Christmas Party. This event is held on select evenings at Magic Kingdom Park, and requires a special event ticket. I had the pleasure of attending Mickey's Very Merry Christmas Party last December, and it was a festive evening of celebration that I will not soon forget. Please keep in mind that you may need to purchase tickets to Mickey's Very Merry Christmas Party in advance of your visit, as some nights do fill to capacity.
I hope that you and your wife have a most magical vacation, Mark! If you have any additional questions about Christmastime at Walt Disney World, please do not hesitate to stop back by the Moms Panel. Happy planning!
