In December 2000 we arrived at 6:00, thinking the show would begin at 7:30, but since we had checked the schedule, it had been moved back to 6:30, with another show added at 9:30. So we had to choose between standing room only (which was the sign at the entrance read) or wait three and a half hours for the next one. We went on in. Standing room only turned out to be seating right behind the dinner party section, and the pre-show (two guys) were just getting the crowd to do a slow motion wave.
In December 2002 we arrived at 4:00 for the 6:30 show. Crazy? yes, but we'd completed all the things we'd wanted to do at the park, and shuffled by the entrance right as they began letting people in. We got the center row, right at the rail and taped most of the show, which we enjoy again and again at home. There were only single benches at the rail, and then the front walkway behind them, before the rows began. This meant we have nothing between us the water on the tape. Will we hold down a spot for two and a half hours again? No. But it was worth it then, since we were tired, wanted to eat and rest, and were able to do that and have the best seats in the house. The center seats are much better, since the timing of the music and the special effects are set for the middle.
(And even the best seats are still really hard, metal benches that were freezing. We had brought sweatshirts and coats, and really felt for the folks who had gotten there almost as early as us and sat in the nearly freezing temps. With the wind coming off the water, I'm pretty sure the chill was below freezing! For only $30 you could buy a blanket!

Anyway, the year-of-the-long-wait also did not include any pre-show act, unless you count the teeth chattering, blue-skinned people who kept coming up to the vendor and asking how much the blankets cost. Most folks passed, but she did sell a lot of beach towels (a $15 bargain!)
