In my opinion all depends on if you want to do business or just be seen.
It seems to me the people that go to all these ( 7/8 in a year) show it's just for branding and be seen...As far as business goes you can do that using Skype, email, phone or if you really have to your fly to the guy and th meeting will be for sure more productive than at the show.
The best show i have been so far in PHOENIX.
