Also, as I've already pointed out, it's unlikely that Steve would have sacrificed the winner's privacy (I'm pretty sure there's an option for the winner to handle the airfare and hotel bookings themselves) + he could come to the party under a pseudonym.
I have no problems with that, honestly. I just don't really like football and don't ever watch it apart from Brazil's matches on the world cup, so it would really be a waste with me. I think I would probably accept it if it was a trip to watch a CS:GO major championship rather than a football match, for example.
