Bright Suns, David!
I'm Ashley, a Human-droid relations specialist for planDisney, and I'm happy to answer your question about one of my favorite Walt Disney World Resort Experiences,
Savi's Workshop-Handbuilt Lightsabers. The Force must be very strong with you as wielding a lightsaber is an incredible honor and rite-of-passage. The Gatherers at Savi's have spent an astonishing amount of time salvaging remnants and relics for you to craft your custom hilt.
Currently, all Guests visiting from the "galaxy, far, far, away" known as the United Kingdom must call
0800 16 90 730 and speak to a Force-sensitive Cast Member to make reservations for Savi's Workshop experience( you can book your reservation up to 60 days in advance). The location of Savi's is meant to be kept secret to protect it from The First Order, so this is the only and best way to secure a reservation. Please note that wait times have been longer than average lately, so I would recommend calling either earlier or later in the day to lessen your wait.
I hope this was helpful, David and that you can book your reservation for this out-of-this-world experience. If you need anything, please reach out to us, and we can assist you in your future planning needs.
May the Force be with you!
Ashley F.
