Hello Kathryn!
Welcome back to the Disney Parks Moms Panel!
Currently, Fantasmic! is scheduled for 7:00 PM and Star Wars: A Galactic Spectacular is set for 7:45 PM on Friday, February 17, 2017. Honestly, Fantasmic! is a 25-30 minute show, so trying to enjoy it, exit and make it to enjoy the fireworks, stroller or not, is almost impossible. The best part of the Star Wars: A Galactic Spectacular are the projections and laser light show and people start gathering to get a good spot usually forty-five minutes to an hour before the start. I strongly suggest choosing one or the other so you can fully enjoy the show you choose. (Personally, I'd choose
Star Wars: A Galactic Spectacular because with a good spot it's absolutely incredible.)
If your heart is set on trying to view both, you'll want to sit towards the back of the theater and you may even want to leave before the finale (which is a great part of the show.) You will need to pick up your stroller on the way out, as there is a good possibility you won't be able to get back in. You'll notice the crowds already gathered as you make your way down Sunset Boulevard, so take whatever space you can find. While you'll miss much of the projection and light show, you still should be able to see some of the fireworks in the sky.
Have a wonderful vacation, Kathryn, and please let us know if there is anything else we may assist you with.
Magical Wishes,
Lauren
