Collecting Singapore GP tickets on race day

[tom5678]

Bit of a last minute decision to go across to the Grand Prix on the 21st September, too late for tickets to be couriered to me. I have two pages left on my passport and my 2nd passport which is being renewed is unlikely to be returned by then, I therefore need to limit trips across the border. This leaves me picking up the tickets on the day of the race, is it likely to be busy or will everyone else have already collected their tickets? Any advice welcome, first world problems and all that.....
