Welcome to the Disney Parks Moms Panel, Crystal! You must be so excited for your upcoming vacation!
As far as I know,
Jedi Training: Trials of the Temple should be available during the dates of your stay. That said, I recommend keeping an eye on the daily schedules as your dates approach because events and Character greetings are subject to change.
You do not need to pay extra for this galactic experience, but you will want to make sure you arrive at
Disney's Hollywood Studios early to sign up.
Sign-ups for Jedi Training: Trials of the Temple happen on a first-come, first-served basis so you'll want to arrive at the park a few minutes before they open and walk straight to the Indiana Jones Adventure Outpost to register your child(ren). Remember, any child between 4 and 12 years of age who wants to participate must be present at the time of registration.
We absolutely loved watching our son take part in this experience! It's such a fun way for kids to Awaken the Force and face the Dark Side!
Thanks so much for your question, Crystal. May the Force be with you on your vacation!
