Almost any trade show can be VERY expensive for a exhibitor. I've attended and staffed quute a number and managed our display at a couple.
Things are tough all over, and its really hard to justify these expenses when many of these companies are among the ranks of those letting people go.
at a major event, like the Consumer electronics show. a simple pedestal with a laptop computer will cost the displayer as much sa 5-10K, and surcharges for everything (signage, electrical, internet access etc.) THEN, if you want more than one person working at that pedestal, it can be half again as much for the extra people simple to WORK. put on top of that the travel and lodging, display shipping there and back, and all that goes with it, its not hard to spend $50K on two people for three days at the smallest of displays.
whats worse, as the entire show shrinks both in displays and public attendance, those who DO cough up the bucks to participate end up standing around talking to each other.
It's tough out there. I'd rather see the money not spent and somebody perhaps keeping their job with the savings.
