Check-in procedure question

Hopefully one of the moderators can answer this!

So to be certain: what shall be the procedure for check-in on Friday? Obviously it will involve visiting the check-in booth to obtain a badge, but will we simply require an ID and/or the credit/debit card we used to make the purchase? Or we were meant to be mailed something to turn in? (I may not have gotten such, in the latter case, despite purchasing a ticket. Would a printed proof of purchase suffice in that case?)

Just want to sort this out now to avoid any unpleasant surprises at the door.

You'll need your ticket as well as the ID of the person who purchased them. You can get a printout of the ticket by visiting Eventbrite, or you can download the Eventbrite app on your phone/tablet/etc.
