Dear Donna,
Thank you so much for visiting us here at the Disney Parks Moms Panel! I always love to chat with a fellow New Jerseyan!
Yes, at times the evening shows such as
Star Wars: A Galactic Spectacular, have start times slightly after the park officially closes. This means that no attractions will be taking on additional guests but that there will still be quite a few folks still in Disney's Hollywood Studios for the phenomenal show! I recommend gathering with your party somewhere close to the stage, but don't worry if you're not too close, because the show is quite visible even from a far distance! There is no additional charge for the show, besides park tickets.
If you are interested in an extra special experience, you could consider
Star Wars: An Intergalactic Spectacular Dessert Party at Disney's Hollywood Studios. That combines delicious snacks with preferred viewing for the fireworks, and it's lots of fun!
Hope that helps with your magical planning! May the force be with you!
