Hi Stephanie! Your family must be so excited that your Disney vacation is just around the corner! The
park calendar is showing Extra Magic Hours for Hollywood Studios on February 23 from
8 a.m. to 9 a.m. during your trip. The park opens at 9 a.m. on the other days.
The best tip I can give you to ensure that your son will be chosen for the
Jedi Training Academy is to arrive at Hollywood Studios before opening, and when the park opens, go straight to the Jedi Training area outside the ABC Sound Studio to sign him up. Pre-registration for the Jedi Training Academy show usually begins at 9 a.m. each day, and passes are given out for all shows that day on a first-come first-serve basis. The children must be present to register, and if they are not selected for the first show of the day, they will be given a slip indicating the time to return later that day for their Jedi training.
Since you're visiting at a time of year when the parks aren't extremely busy, I think there's a good chance your son will be picked to learn lightsaber skills from a Jedi master! May the force be with you!
