You are not likely to see your name listed yet, if at all...
The Eventbrite is to reserve your right to enter in good time, it is not a reserved entry...
You need to get to Aspers in good time on the day of the event with your Eventbrite receipt and pay the required entry fee. This then ensures you a seat to the event.
Nobody has said yet if you could maybe arrive on Friday night and pay for events on Saturday & Sunday with your receipts, if they are not busy when you arrive they might accept your payments...
I have three events through Eventbrite and have used them in the past...
