Generally i thought the event was good, but there are various things that really need to be sorted;
Bring back staggered opening with early bird tickets, it looked like you had the entire capacity turn up and try to get in at 9. I arrived at 830 and did not get in until about 1045.
Over head hanging signs would make navigating and finding areas much easier.
Put 'you are here' markers on the maps.
Level 1 in particular was very over crowded and hot.
Give the guests more signing time.
Perhaps a dedicated hall with tables and chairs and food sellers for people to chill out, like most other events these days.
It would also have been nice if someone had gone up and down the queues in the morning letting people know what was happening and pulling people out who were going to miss photo shoots etc.
The outside queue management that was run by Olympia worked very well.
