From the link above, I found the following quote:
"In addition to the spotlight arena presentations, this year's Expo will feature screenings, celebrity panels and autograph signings, eye-popping pavilions, exclusive insights into TV shows, theme parks, animation, Disney history, and
more, to be announced in the coming weeks. Arena presentations will
include:"
All this indicates to me that there is much more to come. However, at this point, it is probably not a good idea to encourage people to come to the Expo since it will be more heavily attended than the last one. So I think you're both right, the less days to go the better, it is not worth the hassle to attend or the fees!
I live 25 minutes away and I've got a hotel room and sprung for the Premier pass, but perhaps it's not worth it for anyone else to go!
Maybe those of us who were at the first one are expecting too much, but if you didn't experience the first one you can't imagine how many surprises and great presentations they worked into every day. I kick myself for being too tired to stay for any of the evenings. If I had missed any one day of that show I would have been more than disappointed, however, I had friends who I thought were Disney fanatics that went one day and felt it was enough, so I guess to each his own.
