I think it would also be advisable for people to pre-plan their exit from the venue.. After going to the opening and closing ceremonies of the commonwealth games here in manchester, it's only fair to say that 40,000 people all trying to leave at once is somewhat an affair to not only organise, but to get through. So people need to be considerate and patient when they go to leave the venue and to not think that they've got to all get out at the same time.
And please make sure that you know exactly where you entered the venue and you take a mental note of where the exits are!
