I can't answer your question in regards to the second showing (we went to the first), but we (party of 8) just had lunch there on 8/1 at 12:30. We didn't get out of there until after 2:30. We had a fair amount of time in between courses (apps, main, dessert) to just sit and talk so I don't think it was because we are slow eaters

Not sure if it was because the restaurant was busy or what (we ate in the Hollywood room, so it was just us and one other family, several open tables in there). Not sure if everyone experiences such a relaxing pace, but I thought I'd mention that.
Also, our group was 5 adults (4 adults & a 14 yr old ordering off of adult menu), and 3 kids (12 yr old ordering off kid menu, and 5 & 8 yr olds). Our server told us the kids could order whatever off the kids menu and it would count for the ticket. Orders from the adult menu need to be the app or dessert & entree (and that she'd allow a salad as an entree). Not sure if all servers will say that, but I was sure glad ours did, it would have been a lot of waste if the kids all had to order a kids dessert too (they didn't mind skipping dessert because they had ice cream right before lunch

).
And since this is the WOC superthread, I wanted to share a pic of where we stood that night. It was an amazing view! We were back far enough to take it all in, and caught glimpses from the surface of the water up now and then too. I was a little worried about the massive black lamp post in the way, but it wasn't an issue at all. We were also told that it was dead center of the show, have they realigned it? The pic from the beginning of the thread shows we were off center.
Apparently, we were too entranced with the show that we didn't get any pics until it was over
Stood at the red dot, on the steps along the railing. This section (going to the right of us) was the only section I was offered. I was told that the preferred dining down front past the circle was WCT, but I was welcome to go there if I wanted. The section in front of us may have been preferred dining as well, it was hard to tell what the CM was pointing at, but it looked roped off and stayed empty until close to the start of the show. I sat down right at 8 when they opened it and was pretty much alone for the first half hour (there were a few other families along the rail down the way). Directly to my right was 2 or 3 benches along the railing taped off for those who needed them (these filled up quickly). I was also a little surprised that we got "wet" here (not soaked, just felt it). Not just the mist from the high fountains, but from the little fountain in the garden area just in front of us.
I hope this helps someone. I was very pleased with our view (being vertically challenged at 5', that's a big deal!).
