I know what you mean, I got up at 3:45am New Zealand time to try and get the sat afternoon tickets, and tried for 2 hrs, and couldn't get one. One is all I wanted.
I did manage to get Saturday evening, but I would love to swap that for an afternoon one.
Signed up for the American Homebrewers association, booked flights from NZ, hotels etc. All to come for the afternoon session, but despite hours of trying and refreshing, had no luck, very disappointing.
