This may be why this event is a 'Minimum' of 25,000 whereas the 1st event was a 'maximum' of 10,000. They may need at least 20,000 people to be present when the evacuation takes place (That's a guess as I'm sure they will have allowed for the fact that some will leave early)I would’ve thought so. It’s something I thought would have a pre-requisite stipulating x amount of people need to participate in an evacuation, in order for it to be valid, hence why I’m wondering if they even allow people to leave before we all have to. I’m going to the match Sunday, so will find out first hand how it works out.
I expect it to be around the 80 min mark.
