Hi Marcy,
Welcome to the Disney Parks Moms Panel! The Force must be strong with you. I sense that you are being drawn to Disney's Hollywood Studios!
It may be possible to do both shows, but a number of stars must align. When I checked a few dates in December, it looks like
Jingle Bell, Jingle BAM! is 30 minutes prior to
Fantasmic! Since Jingle Bell, Jingle BAM! is about 14 minutes in duration, you could leave just as the show is ending and hustle to Fantasmic! Whether or not you actually make it will depend on the crowds at the time of your visit and your speed walking ability.
Jingle Bell, Jingle BAM! is one of my favorite nighttime shows. The projections and special effects are truly mesmerizing! Choose your viewing spot carefully because you will need to exit quickly. Be sure you know how to get from one location to another prior to needing to make the mad dash in between shows. Fantasmic! does offer Fast Pass+ and you could also get reserved seating for the show by booking a
dining package.
Marcy, remember that show times could change or shows could be cancelled due to inclement weather. Always double-check the show times as it gets closer to your visit. Be sure to also check out
Sunset Seasons Greetings and Star Wars at Walt Disney World Resort experiences. On our last visit Kylo Ren tried desperately to recruit our girls to the Dark Side. They chose the path of the Jedi instead!
Magic, memories and Minnie Mouse hugs,
Donyell
