I'm really hoping to make it to the 2010 one! I have plans to go so not much could stop me
Only advice I have for you right now is if you plan on renting space- you'd obviously have to get a head count a bit earlier than normal to see what sort of accommodation is needed.
I'm definately willing to pay an entrance fee. I know you feel bad charging people but hey- if we're willing to pay, let us help you!
Also if you can, maybe check your local VFW, they're usually attainable for low cost (sometimes you do need to know someone to get one of these places. Not all are like this though lately)
Sometimes places sound good over the phone and then you go there and it's not as big as they say it is :(
