I've been going since 1996. It's never really been run well in the past 15+ years until this year.
Perhaps due to firing the old con chair, or better internal organization, or by using hired professionals and having professional theater people, every event I went to ran on time and had few if any glitches. Of the glitches, there was one I found: Not enough spotlight on Yohko Ishida. I felt more let down by Famima!! which was unable to supply enough onigiri and sandwiches after being thoroughly raided on Friday.
Though, unlike past years, I didn't try to go to many events, aside from concerts. Instead, I spent time at "Artist's Alley" helping with the sale of our doujinshi and T-shirts. Although sales were good, there wasn't a whole lot to sell actually and really what it was was a place to hang out. Hanging out is what all the other attendees are there to do. We know people from Sakura-con and some industry people. Hitomi also now knows some Momoi fans from online that we met up with.
I'm disappointed I didn't attend more events and do more things. There was an industry event that we went to instead of Cosplay (Masquerade) which turned out to be one of those events that sounds good in theory. We were invited to The Edison, an ultra-classy bar with potentially interesting industry people, though the experience was plauged by extra-loud music. The effort required to converse over all that music made it not worth it. Returning back to the hotel, Hitomi met up with some people from a Japanese publication covering Anime Expo and we had an interesting discussion on the state of fandom, in Japanese.
We all agreed that younger fans don't really care much about where anime comes from or the history or old shows or for that matter having to pay for shows. But some other interesting things: Fashion (cosplay) is an important focus of fans; Goth-Loli not Moe' style is popular; Japanese guests aren't that important to fans. With fans getting older, it's become sort of an all-ages, family sort of event. Unlike back in 1996 where I was a college kid and everybody else was too (or just about). 30-somethings are running a convention for teenagers, which might explain why this year was more organized than ever.
