Greetings, Sarah, and welcome to planDisney!
Thanks for coming to us with your question. It sounds like you're about to have a fun-filled evening at the Disneyland Resort that takes place a long time ago in a galaxy far, far away! Congratulations on getting tickets to
Disneyland After Dark: Star Wars Nite and I'm really excited for you!
I'm happy to report that you should be able to bring your lightsaber into Disneyland Park with you as an accessory to your costume. As long as you are in compliance with the
Dress Code and do not bring any
prohibited items through security, you should be fine. The final decision will be at the discretion of the security Cast Member, of course.
In fact, there's even a lightsaber event during the party at the Millennium Falcon for a
Resistance Show of Unity (check out all the lightsabers in the first picture!). That's going to make for a fantastic photo!
Sarah, I hope this answer helped to put you at ease and I wish you an out-of-this-galaxy good time at
Star Wars Nite! Please let us know if you need anything else because we'd love to hear from you again!
May the Force Be With You,
-Al
