If you have pre paid tickets then there should not be an issue. I believe the problem today was the pay on the day queue.
Luckily I turned up at 9.05 and just walked in but I was stunned by how big the queue was.
I love these shows and have been going to them for years but I have to say that today was almost too busy to enjoy.
I gave up at 3.30 after it took an hour to get through Carrie Fishers queue.
I will be back at six for the comic event, I'm hoping this will be good as we have no details on what is due to happen
Hopefully tomorrow will be a lot quieter as I still have a lot of autographs on my list to get.
