Tabletop Queue Organization
Instead of keeping the doors between TT and the Expo closed until the Queue clears, the TT entrance has to wait around.
There is no signage pointing this out, which makes TT more difficult than last year. I would have gone to arcade or console or even the queue (even though I don't care about the Expo today).
I know it only has one day of applicability left, but something to watch for.
