Well hello, Beth - first I have to tell you that is a fabulous time to visit Walt Disney World - especially since the 11th is my birthday! ;) We usually plan a trip during that time as well and I just love all the holiday decorations and events going on.
Unfortunately the Disney parks calendars have not yet been updated for that time period. With all the new events for Summer Nightastic, the calendars are just now getting updated for the summer, so it'll probably be a few months until all of the December hours and events are added. However, I didn't want to let your question go unanswered. The best plan is to just keep checking the calendar for
Disney's Hollywood Studios for December and if you still don't see anything soon, ask us again and we'll see if we can find an answer for you.
Good luck with the rest of your planning - I hope you are fitting
Mickey's Very Merry Christmas Party in because it's a wonderful separately ticketed event! My family attends every year - we just love the snowfall on Main Street, USA and the special Very Merry Christmas Parade!
Come visit us again with any other questions you may have! ~Suzannah
