Hello Emily,
The
upcoming Jingle Bell, Jingle BAM show sounds amazing, doesn't it? I sure wish I was going to be able to see it this year, but my Walt Disney World travel plans come just before its debut. But, I am so glad to hear that you will be there for this special time of the year. You are going to love all the wonderful seasonal touches throughout all of the theme parks.
While we have not been given specifics on show duration for the
Jingle Bell, Jingle BAM! holiday show, many of the recent projection shows such as Celebrate the Magic and Star Wars: A Galactic Spectacular have lasted between 10-20 minutes. If this show has a similar timing, the two shows could overlap. I would say that you might have to choose between the two nighttime
entertainment options at Disney's Hollywood Studios. If you are really hoping to catch both shows, I would recommend going on two different evenings. If you have tickets with the park hopper option, you would not have to spend a whole entire day at Disney's Hollywood Studios again. You could simply head over for the show you did not see.
Whatever you decide, I wish you a very merry jolly holiday on your magical vacation.
