Hi Sharkie
It's likely that some people will arrive many hours beforehand, and others will arrive closer to the time that Mitchel will be there (although still early).
What you will need to do is
try your best to get there as early as possible ... but you have to understand that you will probably have to wait in line for ages regardless of whether you arrive earlier or later.
You don't want to arrive too late, in case the line is long and Mitchel is only going to be there for a certain period of time. It's possible that if he doesn't get through everyone, you may miss out
Good luck! I hope you do meet Mitchel
