We went Sunday, didn't make it into the park until about 9:15, went straight to the sign-up area (actually wandered a bit because it had moved from a couple years ago), and got in line. We only waited about 20 minutes. But by the time we signed up, the earliest slot available was 4:10 (which we took), and then there were like 3 slots after that. The older kids fought Vader, but my son who is almost 7 was put in the younger group so he fought the sister. When you show up for your slot, they have the kids pick a dot to stand on. There was a front row and back row. My son was on the front row. Not sure if that had anything to do who they fought, but just an FYI. All of the kids were given a pin at the end which my son proudly displayed for the rest of the day. We tried to have him do this when he was 4 and it was a no-go, but this time he was very excited about it, and it ended up being the highlight of the day for all of us!
