Hello there, Amanda!
Thanks for traversing the galaxy to bring us your question! Do my best to help you find an answer, I will!
Gaining access to
Savi's Workshop is no small achievement, I'm glad you were able to secure a reservation! After inquiring with some fellow scavengers on Batuu, I have confirmed that there is no way to alter the number of people on your reservation on the
Disneyland Mobile App or website. Is there any
additional availability at the date and time that you need? If there is then you can make a new reservation just for you and cancel the prior reservation. But I wouldn't cancel yours until you've booked a replacement! If there isn't any availability then I recommend you reach out to the Jedi Counsel through Guest Services at (714) 300-7805 to ask for some assistance.
Please remember that you must cancel any unwanted Savi's Workshop reservations one day in advance so that you won't be charged. Skipping out on a reservation is not the kind of rebellion that we're looking for!
Will anyone in your party be wearing a
MagicBand+ during your travels? If so, I recommend trying out Star Wars: Batuu Bounty Hunters! It's a great way to explore, and we often find that we meet fellow bounty hunters. Some of them are quite infamous, such as the Mandalorian!
I hope you have an out-of-this-world experience constructing your personal lightsaber, Amanda! May the Force be with you!
Keep moving forward!
Amanda
