One thing I always get bothered by at Gen Con is people not getting enough practice in. With that in mind I'll be spending all evening Thursday fighting people with my books, bring your tournament book and lets fight. I may even try to get this set up as an all day event as well.
There are pros and cons to this.
if you make it an all day event, it gaurentees you table space which is always a pain in the ass to find at GenCon. That's one of the bad things of Gen Con is there is little to no room for any open gaming.
If you make it an event, it has to be paid for. they charge for space by the hour which is reflected in Ticket price. That is why a 1 hour event is $2, and the MW tournament, an 8hr event is $16. If this is an "event" for all day, say Thursday 10AM - 10PM, its going to cost somewhere around $24 a person. Also how many "seats do you request? 10, 16? I'm not sure if that has to be paid for in advance and you get the ticket money back or something, but there is definitely a cost associated with it.
We're still debating GenCon because the cost keeps going up every year. And if we come, It'll be with the Wife and the baby, so I probably would be able to do an all day thing, but maybe drop in for 2-3 hours for a game or 2. I'm not going to pay $24 to drop in for one / 2 games.
You'd probably be better off trying to wing something Wednesday and Thursday nights in one of the local hotels that AW is putting you guys up in.
