I think the conditions can have a huge impact on one's experience. We attended on June 29th, a Tuesday. The Sunday show had been cancelled due to weather, and the resort was pretty full-- completely full for points-based stays, and so it was very crowded. That meant being seated very far back on the lawn for our party of two. We bailed after about five minutes because we couldn't see at all due to the distance and the number of people letting their children stand so that they could see. We had already attended a luau and the Ha! show at the PCC, so we just weren't interested in sitting uncomfortably on the ground on our mat surrounded by people with little room to shift, etc., and not be able to see over a four year old...
On our way out, we ended up lingering near the exit and DH was able to sit down on an unused chair. I stood up against a palm tree. The content of the show was very enjoyable in the end. I was disappointed, though, that when the characters finally came out, that again everyone was on their feet, so seeing was really not realistic, and photos were impossible. If you had very close seats, it might have been very different.
Moral to the story, if it's crowded, definitely line up really early.
