I think it would be better to find out how much it is going to be to get a conference room for the days that you want THEN figure out what you are going to charge vendors and attendees.

when you come right down to it its needs to based on size of space and what kinds of advertising you are doing, as well as what its costing, to do anything else is going to put the brunt of the expense on the attendees.

I could be wrong and not know your thinking so try not to get mad at me ...
