First off...it's an enjoyable experience just to be around so many people of like-mind in the same industry.
So you will have fun.
And as I understand it, this year will be the return of the Show "Floor" after several years absence.
I personally have always enjoyed the shows...putting faces to names, networking, meeting new people, going to the parties and socializing.
You will be surprised at how many contacts and potential business deals you'll get involved with just by being social.
