Hello James!
I sense the Force is strong with you, so the
Jedi Training Academy sounds like the perfect experience for your young Padawan. You are correct in that you need to head straight for the ABC Sound Studio to get in line shortly after park opening. This attraction is "First Come, First Sabered," so the earlier you can get there, the better. After entering Disney's Hollywood studios, keep left around Echo Lake and the ABC Sound Studio will be on your left, just past the Indiana Jones Epic Stunt Spectacular. You can find its exact location on this
map, under the blue marker. I hope the High Council selects your Junior Jedi Knight to participate in the training event and that she learns how to defeat the Dark Side.
Please let me know if there is anything else we can assist you with.
May the Force be with you,
Lauren
