Howdy Christine!
Jedi Training Academy has recently been updated and is now
Jedi Training: Trials of the Temple. This interactive experience allows young Padawans to train with a Jedi and even come face to face with Darth Vader and a new villain from the Disney XD series, Star Wars Rebels. I have not yet experienced this re-imagined training with my children, but I know it will be extremely popular.
Depending on how crowded the park is, the slots for the Jedi Training may fill up very quickly. When I did experience the older version with my daughter we went straight to sign up when the park opened and we were placed in the third show of the day. The shows run about every half and hour to every forty minutes. I would ask your boys what is more important to them, to experience the Jedi Training: Trials of the Temple or ride Toy Story Midway Mania with a shorter line. A suggestion to save time would be to book Toy Story Midway Mania as one your 3 Disney FastPass+ selections you pre-reserve before you arrive, and use the morning to go sign up for the training.
Christine, I hope you have a great time on your upcoming unforgettable vacation. If you have any other questions please stop by again. All the Disney Parks Moms Panelists love to help out whenever we have the chance.
Have a Force Filled Day,
~Jen
