I missed out on a couple of guests (the perils of a single day and needing to get a coach back home in the middle of the afternoon) and I'm sadly cursed to always have a couple of autographs go horribly wrong, but overall, great success.
Patrick Stewart's talk was wonderful (Patrick: "I introduced America to double teabagging!" Shocked young woman next to me: "I'm sorry, what?!"), and I hope he is able to return after the release of the show, like he mentioned. Loved hearing how Picard would have sounded with a French accent.
I particularly enjoyed chatting to Brent Spiner, Sonita Henry, and Michael Ensign. I generally don't expect more than a couple of seconds with guests due to the nature and requirements of the event, but managed to have nice little exchanges with them all (I sometimes think bringing something that relates to other work they've done helps with this - I'm still buzzing over how pleased Jason Isaacs was to see a copy of Black Hawk Down last year).
Side note: I think Wilson Cruz would be the most fun on a night out. That guy's boisterous as hell and he really made me laugh
