I know this question has been tossed around a lot over the last few months, and I thought I would share what our experience was a few weeks ago. We arrived around 8:05 for the 8:45 opening. We were third in line. We walked quickly to Jedi sign-up, and there was a short line there. When we came to get a time, he was still taking times for the first show. I asked politely if I could have a later time, and he asked which one. As he put our name on the list, I noticed there were others that had signed up for later shows before the 9:20 show had filled in. So I guess this means it all depends on the CM signing people up for the shows, and it doesn't hurt to ask. We made it to TSM and were off by 9:20. We then went to meet Buzz and Woody which had a 30 minute wait already! That was the only line we waited in the entire trip, so I am not complaining. It was worth the wait too! Anyway, just thought I would share our experience since it seems like it is very inconsistent!
