Bright Suns Dean,
I'm Ashley, a Human-droid relations specialist for planDisney!
Savi's Workshop-Handbuilt Lightsabers is my favorite experience at Walt Disney World Resort, so I am thrilled to answer your question. I still remember the day I built my lightsaber, and it is proudly displayed in my home with my other cherished possessions.
Currently, Guests visiting
Star Wars: Galaxy's Edge from the "galaxy, far, far, away" known as the United Kingdom must dial 0800 16 90 730 and speak to a Cast Member to make reservations for Savi's Workshop experience. Savi's is kept small in order to avoid detection by the First Order, so spaces are incredibly limited. You can begin booking Savi's up to 60 days before your proposed date, so I encourage you to secure a spot early. Lastly, call times to speak to a Cast Member have been longer than average so try to call either earlier or later in the day to minimize your wait.
If you need anything, please reach out to us here at planDisney!
'Til the Spires,
Ashley F.
