Okay, here's my thoughts [rant]:
Celebrity photographs -- how much time is wasted in the signing lines with people contorting to try and have pictures taken with the guests? They usually look lousy, are impractical, and create bottlenecks. What would be great is to do what a lot of the other cons do, and have celebrity photoroom, offering scheduled appearances with a professional photographer on hand. They could even have a minor set put together (eg. the Collinwood or Old House mantle) to pose against, with each of the celebs scheduled over the weekend, with the proceeds going to a charity.
So yeah... I don't like the idea of receiving all the tickets, etc, through the mail, as overseas people like myself have to risk not having them arriving before departure, and you're bound to have heaps of people whining: "Wah! Where are my tickets? I've lost/dropped/eaten them... wah! etc..."
And cut down the signing lines. Stop people from re-queuing -- have the actors sign for now more than two hours at a time and cut it off there. They could sign all weekend and people would still be queuing up to get the gazillionth thing signed. It's insatiable, so why bother trying...
I'd like to see more dramatic readings, skits, etc -- I think it would be great to have a staged reading of some DS scripts [maybe some of the abandoned 1969 scripts cited in the 2000 Almanac, maybe with music too]
Erm... that's it
