Last year for Plumbers, the venue cost us $37k and the breaks $132k (including a lunch buffet, which was a requirement of the venue rental). Given we had 500 attendees, that, alone is $340 per head already. Now we could cut out the continuous tea and coffee ... and the espresso machines you all raved about last year cost us about $7 per shot. But it's not just this, it's also AV (microphones and projectors) and recording, and fast internet access. That all came to about $100k last year (or an extra $200 per head). So you can see, running at the level Plumbers does you're already looking at $540 a head, which, co-incidentally is close to our attendee fee. To get to $300 per head, you lot will have to give up something in addition to the espresso machines, what is it to be? James
