Welcome to planDisney, Karen!
I bet you're so excited about traveling to The Happiest Place on Earth for the Holiday season. Disneyland Resort does a stellar job at making everything look, feel, taste, and smell like Christmas. I know you're going to have a magical time. One of our family traditions is stopping by
Plaza Point in
Main Street, U.S.A. at
Disneyland Park and purchasing a Christmas ornament. Over the years, we've built quite a collection. We always reminisce about past Disney memories whenever we decorate our Christmas tree.
I can understand why you're eager to see
Fantasmic! (my favorite nighttime spectacular) and World of Color. The regular World of Color show is actually being replaced for the Christmas season by
World of Color - Season of Light.
Although the schedule for the week of your trip hasn't become public yet, I would anticipate World of Color - Season of Light being shown twice a night (9:00 and 10:15 PM) every day of that week. Same with Fantasmic! On really busy weeks, like Thanksgiving, Disney usually shows Fantasmic! twice a night (9:00 and 10:30 PM) every night. However, since the schedule hasn't been released yet, this is my educated guess. You'll have to just keep checking the Disneyland Resort website.
I hope that's helpful, Karen! Thanks for stopping by planDisney.
Mike
