In holland they kept on putting people in the first pit. I asked them how many (since they were counting) and they told me they would put 2000 in the first pit. that is probably the most people I've seen in that front pit.
In munich there was no golden circle -ticket, but there was this same pit. they only let fanclubmembers in that front pit and there were 1000 people in the fanclubline waiting when we got in. Maybe they filled it up a little just before the show, but I think tops 1500 people.
