Hi there, Jill!
My favorite time of the year at
Walt Disney World is during the Christmas holidays, and my family and I have always loved the Mass at
Disney's Contemporary Resort. It has been the best beginning to a magical Christmas morning.
While an official announcement for this year hasn't been made yet, in years past, there have been two Catholic Masses offered. The first is at 8 AM, then there is usually a second Mass at 10:15. A Protestant service usually takes place in between the two Masses.
I also wanted to mention that right near Walt Disney World, and a quick Uber or taxi ride away, is the Basilica of the National Shrine of Mary Queen of the Universe. The absolutely beautiful Church has a more traditional Christmas Mass schedule, including a midnight Mass. If the Christmas morning Masses don't work with your schedule, this is a really wonderful option.
Have a magical vacation.
Anna
