Welcome to planDisney, Stuart!
I'm really sorry that you're having trouble booking
Savi's Workshop. The First Order has been working hard to prevent communication between Batuu and the UK. The last thing they want is more UK-based Jedis coming to Black Spire Outpost and building their own lightsabers. However, the Force is clearly with you. Let me give you some secret information that I've received from my friend in the Resistance.
It seems like you've been trying to book using the My Disney Experience Mobile App. Unfortunately, UK-based Guests can't currently book this experience using the app. The only way to book
Savi's Workshop is by calling the
UK freephone number for Tours & Recreation and speaking with a friendly Cast Member. I'll be wishing upon a star that you'll be able to get a reservation, Stuart.
Since you'll be in Star Wars: Galaxy's Edge, you've got to stop by
Docking Bay 7 Food and Cargo and try their Felucian Kefta and Hummus Garden Spread. Then head over to the
Milk Stand and enjoy a big gulp of that blue milk.
I'd be interested to know what your favorite ride is:
Star Wars: Rise of the Resistance or
Millenium Falcon: Smuggler's Run? Personally, I've got to go with the former. However, I must admit, the line in the Millenium Falcon is an attraction in and of itself!
Till the Spires, Stuart. Thanks for stopping by planDisney.
Mike
