I did the 8:15 (only) showing of WoC on Wednesday.
I got my fastpass by entering through GCH (stayed onsite). We arrived around 8:40 and were the third group in line. This wasn't really necessary- everyone got in and got their fastpasses within the first few minutes after 9:00. Then we still had 25 minutes to wait for Soarin to open.
Pass was blue and return time was 7:00-7:45.
I had scoped out the crowd situation the night before. At 6:30, no one was even milling around the area. At 6:45, there was a good size crowd. We headed to the area at 6:35. A line had formed, but I knew (thanks to this board) that the line didn't count- that we'd be behind a barrier that wasn't yet in place. We hung out and waited. At 6:40 cast members brought out a barrier and everyone pushed and shoved to be at the front. We were smack in the middle and about 3 layers back.
A tiny hole in the barrier was opened just before 7:00. There was a ton of pushing and shoving to get through the opening- honestly, I've never seen such chaos at Disney. What are they thinking with this?

Getting a stroller and 4 people through was awful and we were all separated. Luckily we had planned ahead and all knew to get in and immediately turn left.
We headed to the bridge. The railing of the bridge filled quickly- about 10 people beat us there and the rest filled in fast. However, the area behind us filled in much later. The same thing happened down below- rails filled fast.
Pre-show started at 7:45, WoC started at 8:15.
The show was great and our view was pretty good (there are some definite pluses and minuses to the bridge, but it worked for us and our nervous kiddo to be far away from the action).
The whole thing was a hassle and required a lot of waiting, but it was worth it!
