Ditto .. not only for the reason arkyt mentioned, but because there seemed to be quite a few “flakey” promoters there. 
Several of the casino representatives were full of a lot of promises, but never followed through on anything. They went out of their way to pull people aside and find out if you are affiliated with their group. They seem so eager to have you promote their casino .. offering you a variety of back end options for your private labels .. customizing templates for you, and more.
Then after the convention .. poof .. they seemed to disappear. 
What’s that all about? Why waste my time or theirs? You leave at the end of the day feeling like you made some good contacts and that good things are going to happen for the mutual benefit of both parties.
What’s the purpose of all the BS? To make me feel as though my time at the convention was well spent?
WHATEVER .. I am doing very well promoting other casinos .. if they want me to promote their brand, or they want me NOT to promote their brand .. doesn’t really make a difference.
I just don’t appreciate people wasting my time with a lot of idle promises only to realize later they had no intention of following through.
They were simply trying to make it look as though they were actually doing something constructive 
Obviously some of these people only came to Las Vegas to drink, gamble and party and were not here to promote business.
That aspect of it was a little disappointing.
