If that`s correct about the doors to the general public not open until 4pm-i think that is a big mistake. I cannot think of any big sporting event I have attended where the doors haven`t been opened at least 90 mins before the start-Parade will start bang on 5 pm as 1st race is on official documents as 5.15pm. I can see a lot of congestion at bag checks etc and just cannot understand any reasoning behind this late opening of the turnstiles.
