Get a good night's sleep. Exhibition halls are often open for seven hours at a time. That's seven hours on your feet, smiling and talking to people. Eight hours of sleep will help you fight off fatigue.

Look the part. Dress comfortably yet professionally. Don't wear clothes you have to keep adjusting and don't be too casual. Do yourself a favor and wear comfortable shoes.

Don't eat at the booth. No one wants to talk to you when you're eating. You'll drive away prospects.

Stand near the aisle. Make yourself available to prospects. Don't hide in the back of your booth space. Make eye contact. Greet people.
