The answer you have given for not doing it is the reason I suggested doing it. I thought it might save time in the long run to know which ones are sold and avoid disappointment at the presentations.
You will be able to see this at the presentations, but we can't make it public as it will be changing with every presentation that takes place. So you may pick your seats, but by the time you arrive for the presentation, they may well have been taken. This is exactly the reason why the club opted for a personal face-to-face presentation, where the staff at the presentation suite will assist you in getting the best available seats to best meet your needs.
