Ahoy there, Gavin, and welcome aboard!
Your
Disney Cruise Line adventure is literally just weeks away, and that's so exciting! And it looks like you'll be combining your vacation with a visit to
Walt Disney World. That gives you the best of two amazingly magical worlds.
There are options here, Gavin. First, you are permitted to bring your lightsaber onboard your
Disney Cruise ship. If you check the
list of prohibited items, you'll see an exception is made for store-bought light sabers, which your
Savi's Workshop lightsaber is. It's under the Toy Exceptions list, so you're good to go there. I myself saw several Savi's lightsabers on a
Star Wars Day at Sea cruise.
Another option is to have your lightsaber shipped home for you. Once you've built your lightsaber and shown it off to everyone, you can walk over to
Dok-Ondar's Den of Antiquities. They can get your lightsaber safely packed and shipped to you back in the UK.
I hope you have an amazing vacation, both with your stop at Batuu at
Disney's Hollywood Studios and on your high seas adventure.
