I doubt people will get turned away.. Sounds just like the airline Business of "Overselling"..
People have tickets, and its a sure guarantee that many people wont turn up, Quite a few people on here for example can't go now, All those arsehole touts who have tickets they can't sell on. And take into count that 2 tickets were issued to every 1 person.. Not everyone will bring that plus 1.
See you all there
