Here is the game plan:

This is based on a trip during April during Spring Break time
1. Arrive before the park opens, they often open the gates earlier then the scheduled time so you need to be ready for that. (Usually, they open them up at least 5-10 minutes early, sometimes 15). We arrived 5 minutes before opening (WORST MISTAKE EVER) and the park was already open. By the time we got to the sign up place, there was already a massive line and we were assigned a afternoon time slot.
2. Be ready to run to the sign-up location.
3. Get in line.
4. The perk to being there early is that you can easily pick your time to fit with your schedule. If you arrive later, you will be forced into the only time slot left if there is still one or have to put you kids onto the waiting list, incase a child doesn't show up to the meeting spot.
5. I recommend taking a after-lunch time slot. This is because you will have time to ride all of the rides and experience all of the attractions with a shorter wait in the morning. Then, when the crowds are at a peak, you have a guaranteed spot to fill that time.
6. Return to the sign-up location at the time they told you to return when you signed up. (They may not tell you, so be there 30 minutes ahead of time. Don't quote me on that though; my memory is slowly fading.

.)
7. Your kids will get their Padawan robes and "training lightsabers" and the Cast Members will walk your children down to the stage with the other children. There, they learn the proper "moves" to do and Darth Vader shows up. Depending how busy the park is and i'm not sure if they retired this, but Darth Maul comes out if it is really busy that day.
8. Get out your camera. If your kids are 11 years old and you don't take them back within the next year, then they will never be able to do it. Remember the age limit is 12 years old.
They will have a blast doing it and i'm sure it will create lasting memories for you and you children.
Hope this helped,
