I also wish to express my gratitude. I only heard about this thing less than a week ago, and was very, very impressed.
I must admit I did think for a while: "oh, well, it's only £5, if it's rubbish I won't have lost much money". Fortunately, £5 turned out to be the first of many bargains I encountered that day.
I've been to things that have cost as much where their "special" guests turn out to be Third Ewok From The Left, and the merchandise dealers turn out to be rip-off merchants. And where the crew manning it are surly, rude and generally elitist because they're in a Captain Picard uniform and you're not, so clearly they outrank you, etc, etc, etc...
LFCC was very professionally run, your staff were plentiful and helpful, and I just got the general impression that it was organised by fans for fans, rather than cynical businessmen hoping to make a quick buck off devotees of TV shows and movies.
I only had enough money to get Jeanette Goldstein and Michael Biehn's autographs. I spent five hours in his virtual queue, which, by the way, is an excellent idea. At the end of the day I only spent about three or four minutes of the day actually queuing up for anything.
So, anyway, thanks and congratulations for an outstanding weekend. I will definitely be keeping an eye on this site to see if you can get any more Alien franchise guests for the next LFCC.
