I will post the positives in another thread as this is just for suggestions.
1. Yes its been said before but merchandise que, 3.5 hours we took to get the stuff and talking not only as a user to the fan fest but as a professional architect the building and merchandise location did not work well and what would be best suited to merchandise selling would be a larger open plan room with separate entrance and exit doors. Maybe a suggestion would be a ticketing situation where you get a ticket with a number on and like in argos you get a number called out. This way you could also give seating to a large number of people waiting. As said as well more members of staff would be great. there were 2 taking money and 2 at the front getting handed filled carries from behind the curtain. I don't know how many staff were behind the curtain grabbing items from the boxes. But in future festivals more staff would mean shorter ques and less waiting for attendees.
