There are plenty of places to meet Santa this holiday season at Disney World:
Santa will greet guests at Mickey's Very Merry Christmas Party and he'll also be one of the stars in the parade. The party runs on select nights until December 18 (which is sold out). After the party ends, you can see Santa in the Magic Kingdom throughout the rest of the holiday season.
You can meet Santa in Epcot at the American Adventure Pavilion between November 24 and December 24. You can also see Santa and his helpers in several World Showcase pavilions telling Christmas stories unique to that country, including France, Germany, and Italy. This is a great way to introduce kids to your own family's Christmas heritage or to that of others.
Santa will be greeting guests starting on Thanksgiving day until Christmas eve from noon until 10:00 p.m. After Santa leaves for the North Pole, Goofy will take over his duties and continue to greet guests through January 1.
Finally, you can meet Santa in your resort lobby if you're lucky enough to be visiting Christmas eve. He'll be there between the hours of 5:00 and 9:00 p.m.
