Yes, I went down to London especially. It was great. I got in free with my Blue Peter Badge! - thinking about it I'm pretty sure I was too old at the time to still be using my Blue Peter Badge!
I've still got some merch knocking around - i'll see if i can dig it out and add a few pics...
It was a pre-digital camera age so I've got a physical album of photos somewhere too!
We were really lucky because we wend just for the exhibition but found out whilst we were there that Ray Park was signing at Forbidden Planet the same weekend!
