The problem there was not having enough security - it's like store giving out free popcorn, and someone comes and steals the whole cart. In the physical world, there would be someone standing next to the cart watching that people take reasonable amounts. In the digital world, nothing was done, so thieves stole a lot.
Not sure what the best solution was to be there... I like the idea of giving people few days to sign up, then randomly choosing who gets to go. Of course this has its own problems - for example you want to allow groups, but this can be abused. Identity verification helps with that, but this makes ticket checking much slower....
It's NL and the everyone has a personal id. There is a national service to validate that, too.
One week accepting of requests - a person can submit multiple id (incl. children). At the end of the period a random lottery with some bias to people registered in the city (in the end the event is paid by them)
