Building a lightsaber at Savi's Workshop in Star Wars: Galaxy's Edge at Walt Disney World is perhaps one of the most ridiculous and exclusive upcharges within Disney's Hollywood Studios.
Don't get me wrong, building a custom lightsaber is a lot of fun and a really unique park souvenir, but the experience required a weeks in advance reservation and roughly $300 CAD to do. For the sake of doing Galaxy's Edge to the fullest extent it was one of the top things I told myself I had to do while visiting Walt Disney World during the 50th celebrations. I'll be the first to admit that not everyone will see the value, but honestly, I still get a kick out of this thing.
