As there is nothing else on the schedule before 11:00, it seems safe to assume that apart from getting a lower ticket number for guest related things, there is no reason to book early entry?
I know that there is not an opening ceremony at 9:00 but I'd still miss it as its scheduled for 10:45 – 11:00, also I realised that I'd get an extra couple of hours hence the topic title asking if there was anything other than the obvious.
Thanks for your replies.
