What advice would you give to a vendor attending their 1st show?

I am going to my first bridal show. I am almost as nervous as I am excited. I was wondering what advice you think is very important to know going into a show.

A few things I have asked, researched, or done in preparation so far are:

• My booth's location
• Electricity is included
• Building a prize wheel
• Getting brochures printed up
• Ordering extra business cards
• Booth set up - I will NOT stand or sit behind the table
• I will have one other person helping me
• Preparing multiple products to show
• Printing extra contracts
