I've been to all the expos so far and have to say 2013 was somewhere below the 2009 (but close!) and above the 2011 expo. I gave it a "I liked it"
SHOWFLOOR: My number one plus is that they rearranged the show floor! They moved the arena line outside and it seems like they spread out all the booths. At the earlier expos the collectors forum and the arena line were where the overflow room for the Arena was this year. It made that area so crowded. That being said, where they moved the collectors forum this year is pretty crammed. It was hard to walk around and I don't think they gave some booths enough space!
MORNING LINES: I never experienced the showfloor lines in the morning but I did think they had the Arena line very organized. The redshirts outside though were so uninformed though. I understand that they may have been hired by the convention center but did they even have a information meeting? A guest was asking one redshirt whether there was a d23 member entrance and regular entrance for the arena and he told her he didn't think so but that the arena line was for Sorcerer's only! When I walked up I heard her saying "I have to pay $1500 to be in this line?!" So I quickly told her how the lines worked. Then I asked him if there was a restroom around and he said "do you have a hotel at the Hilton? That's probably your best bet." hahahah I just had to laugh at all the misinformation I heard given out this weekend.
INSIDE LINES: Most of the lines looked a lot longer than they took - Glendales, Dream Store, Tomorrowland, Imagineering. The only line that was really just insane was the Disney Store line. It took 2 hours all weekend! I left it for last on the last day and although they were out of some products I wanted, I didn't have to wait so long and honestly I can live without them.
STAGEPASS: As someone else said, the stagepasses were very love/hate for me. When I could get one I loved it! No waiting in line. But Other times, the stagepasses were out before I was even out of the morning arena presentations and I didn't get to see anything after that. I think seeing one show a day is a little low if that's all you are really looking to do at the expos. I did hear that you could get in to shows without the stagepasses but I thought it was a waitlist type thing if you didn't have a stagepass so didn't try. Sunday though I was able to see what I wanted to see without waiting in hours of line. So yeah... love/hate.
SHOPPING: I was pretty dissapointed with there offerings this year. Glendales and Disney Store was better IMO, but Disney Store had very few D23 exclusives.
PRESENTATIONS: I have to say compared to the first two years, the morning arena presentations were a little dull. Not because there were no big announcements (I wasn't expecting them anyway) but I think because they moved a little slowly in between movies and they didn't really make a big deal out of any of there presentations. The first year Jonny Depp came out on a pirate ship. This year, actors walked out answered a few boring questions and they left. I think what they were announcing was great, LOVED Idina Menzel and I loved looking at the footage they showed (especially Melificent) but there was just something different about this year's that made it sort of dull for me. Not sure what. They were still enjoyable though.
The smaller 23 and 28 presentations have been great all three years. I think those are the most interesting and fun.
PARKS and RESORTS: Definitely the highlight of the expo IMO. Different from the first two years in that there were no announcements being made here and they weren't showing off things that they were coming to the parks. But I liked this more! You could see how each department works and talk to people that actually work in those departments. If you had a keen eye they had a few hints at things to come which I thought was fun.
The first expo is always going to be my favorite because it was the least crowded so I didn't have to rush to do things and plan so hard and I had no expectations to how things would work. The announcements were top notch but you can't expect that every expo. 2013 was an in between projects year and I think they handled it nicely. The showfloor was vastly improved and I think they still have some kinks to work out with stagepasses and some lines. 2011 expo was pretty much a disaster on the showfloor and arena. They didn't know how big of a draw Marvel would bring and they didn't know how to handle Comic-Con regulars. I think they did a good job figuring that out this year. Overall I still had a lot of fun and didn't have anything to complain about at this expo I just was giving my observations
