I wasn't tracking every minute between the drinking and the miserable weather, but per the phone timeline the old man and I left the ground pretty leisurely at about quarter to 11, joined the queue 5-10 minutes later, and didn't get on the train until midnight, with what I'd guess was at least another 3-4 trainloads of people on each side.
I'm obviously very biased in this regard so I'm trying to be fair re: the delays, but it was significantly more difficult and frustrating than the full house was in Brisbane or the MCG has ever been on an 85k+ crowd. Would be worried about the safety of the attendants if you're dealing with heavy drinking fans dealing with that 3+ times in a row.
