Hello, Chelsey!
Thanks so much for visiting planDisney this week. I sense the Force is strong in your family!
Since you can't see availability on the website, I'll suggest trying the
Disneyland Mobile App. I ran a search now for the week of September 12, and I found a few openings to build a lightsaber at
Savi's Workshop. I think it will work for you, too!
I always recommend visiting
Star Wars: Galaxy's Edge at night, and I think it would be brilliant to schedule your experience for some time around sunset. Batuu really comes alive at night, and many younglings take extraordinary photos with their lightsabers while exploring the area. I bet you'll even hear a ship or two take flight!
I hope you and your youngling have the best time at the Disneyland Resort, Chelsey!
May the magic and the Force be with you,
Julie
