Simplest solution was to sell tickets at a decent price, yes they would have been trolled for making money, but that would have cut the crowd by more then half. They could have done this today giving time to people to buy and resell tickets in black (Like entire season) and everyone would have been happy.
I know, hence the keyword 'some'.
That's a problem of their own making. This is what happens when you blindly throw money at every problem expecting it to fix the issue.
