Well, everyone here knows my Houston vs. Disney opinions, so I'll just say that I'd too rather be at Disney, but Atlanta was a great substatue and did all it could. Anyway....
Food: Good choices, bad prices. Simple as that. I would keep the current system but remove the whole $2.50 thing and have the people refuse to give change thing. If you had a problem with the prices, you could go to the Omni, but that wasn't known to teams, and many found out from second hand comments of teams staying there.
Transportation: We walked, so from the Omni, it was great. Only saw two pannhandlers, but being from Cleveland and having to deal with lots more, I thought it was good.
Walk: Yes, the walk was horrible. Couldn't they just open it up so people could just walk from the first elevator out into the plaza where they had the GM exhibit, and then into the Dome? Or could they just go through where the bots did? Could be improved, but this place wasn't designed for what we inteded it's use to be, but isn't that what engineering is?
Competiton: Overall, great, but I did sense a bit of "Dean is talking to the media about you now. He'll talk to you latter" type thing. I remember back at Disney when he went in the pits to talk and even talked to kids around the competition. Man, I miss those days....
Party: Wayne said it best, get a big name that people that we like and know. No Mandy Moore, get Blue Man Group, or Evenessence. Hyptnotist was great, but mabey if they had him as a warm-up act.
Overall, I liked it better than Houston, but it's still no Epcot. Disney's business was to entertain and handle people, Houston didn't have much experence in that, and Atlanta only did it 8 years ago, it's not like you have to re-invent the wheel every year.
