This was my first Autographica event and found the experience pretty good, I was only there for the Sunday but managed to get all the ones I wanted (5) in 1 hour so queuing wasn't a problem, but this didn't include any astronauts. The guests all were very friendly and found out a few facts about the movies they were in which was great.
Cant wait for the next one in Birmingham especially as I only live a 20 minute drive away
