Bright Suns, Adrian! I see that your chosen path has brought you here to us at
planDisney. Welcome!
Building one's very own lightsaber at
Savi's Workshop – Handbuilt Lightsabers at the Walt Disney World Resort is any respectable Jedi's most important rite of passage, which is why I completely understand your concern regarding the matter. Besides this, it's also very important to have a Droid sidekick from the
Droid Depot at the Walt Disney World Resort following your every move and protecting you from the First Order spies.
At this time, Adrian, all terrans visiting the planet of Batuu from the United Kingdom must
dial 0800 16 90 730 and ask to speak to a Cast Member in order to make reservations for these out-of-this-world experiences up to 60 days in advance. Please remember that you will also need Theme Park Reservations for Disney's Hollywood Studios on the day or days that you plan on partaking in these activities.
I understand that terrans love their datapads (or, as you call them, "smartphones"), but there is no way for these experiences to be accessed via the My Disney Experience mobile app from the UK just yet. This would explain why you've been having trouble using the app. I can assure you that it has nothing to do with Kylo Ren and his Stormtroopers.
Please send us another hologram if you need any more help with the matter. You know where to find us, but remember to keep our location a secret.
May the Force be with you,
Ana Paula
Jedi Master
