Hi Amy,
Welcome back to the Disney Parks Moms Panel! Greetings to a noble family with "crazy" Star Wars fans! We share a special bond as I, too, am a Star Wars fan.
Both
Star Wars: A Galactic Spectacular (approximate time 14 minutes) and
Fantasmic (approximate time 30 minutes) are phenomenal experiences. When I checked August 26th, Fantasmic is listed as showing at 8:30 p.m. and Star Wars: A Galactic Spectacular is listed as starting at 9:00 p.m. Unless you are flying the Millennium Falcon, I do not see how you could possibly do both on the same night. Having said that, show times could change, so keep checking the schedule as your trip dates get closer.
In case you did not know, there is a
Star Wars: Galactic Spectacular Dessert Party. If your Star Wars fans somehow use the Force to convince you to change plans, the dessert party might offer some consolation. Given that the Rebellion needs to expand its forces to bring peace to the Galaxy, you clearly have other priorities to consider!
Since it looks as if you may need quick transit, I suggest that you consider
Disney's Express Transportation Option. Though it cannot compare to the Millennium Falcon, it may be your best bet if you do try to hyperdrive it to another park.
Magic, memories and, of course, may the Force be with you!
