Register early!!!
Register for luncheon meetings to get free meals.
Take plenty of business cards to give to people.
If you want to remember to contact someone after the meeting, ask for their business card and write a note about what you want to contact them about on the back of their card.
A more in depth schedule/agenda will be included in your registration packet. Look through the stuff for things you are interested in.
Dress pants/khakis and dress shirts/ polos are good to wear to sessions and lunches. If you are winning an award step it up a little by wearing black pants and a nicer top or guys a nice shirt and nicer khakis. There will be people in business suits and some in jeans at the meetings.
For the tour, jeans or shorts depending on where you are going. Banquet is always dressy.
