Bright Suns, Neil!
Wow, it is so awesome that your partner is planning on building a Lightsaber at
Savi's Workshop Handbuilt Lightsabers on your upcoming Walt Disney World vacation! I had the opportunity to make a Lightsaber at Savi's Workshop with my son and his wife on my Disney vacation in November 2021, and I can tell you firsthand that it was amazing! It was a Star Wars religious experience!
My recommendation would be to get a reservation for your 12-year-old to build a Lightsaber along with your partner. That way, you could document both of your loved ones crafting their Lightsaber, and it will be a remarkable memory of your Walt Disney World vacation. Plus, you get to take the Lightsabers back home with you to enjoy them at home. My son, my daughter-in-law, and I each built a Lightsaber, and we all selected different designs and Kyber Crystal colors, so each of our Lightsabers was unique.
I hope you and your family have an amazing Lightsaber building experience on your upcoming Walt Disney World vacation!
Til the Spire!
