As an attendee to the Denver show three years ago, I thought the Indy show was 100 times better. IT was well worth my money!!
My friend and I encountered only one major problem, and that was on Sunday. We stayed at the Marriott across the street, and the convention center security people wouldn't allow us across the pedway to wait in the convention center. Hotel management got involved and got the problem resolved.
We expected the long lines on Saturday and Sunday, so we visited the store and got our autographs on Friday. If there was something we really wanted to see (Rick McCallum Spectacular, the archives exhibit and the 30-minute play) we didn't mind waiting in line for an hour or so. I think we waited longest in line to get tickets to hear Hayden Christiansen but we waited with friends.
Overall, I give the convention two thumbs up but I believe the organizers were on the verge of being overwhelmed just be the sheer number of people in attendance.
