Does the Savi's Workshop building experience include a blade in the $200 fee? Initially I'd assumed from discussion here that the blade was a separate charge, but the official description of the building experience ends with:
"Finally, the Gatherers will masterfully connect your hilt to a 31” lightsaber blade so you’re ready for anything the galaxy puts in your path!"...
No mention of the blade being a separate charge, or their being collected by employees the way that the extra hilt parts are. Plus it feels like it would be awkward if guests had to forfeit their blades at the end of it all.
