Organizers should've used the Dome for the opening ceremony program (and the concert) to accommodate everyone. I've been to C1 and C2 and still haven't made it to the opening ceremony but that's by choice. We've headed to the store first both times.
Again, I was fortunate to get Carrie Fisher's autograph last fall. She came to Louisville for a conference and a friend took my slave Leia figure to get autographed.
Yes, the dealers were offering the buy the figures early Friday. When my friends and I were in the store area, it was mostly vendors, not fans, buying merchandise which surprised us. They said stop by their booths. They were offering $25 but on their websites they're selling them for $85.
I didn't sell any of mine to vendors.
