Is there ANY value to "guru" seminars?

[Rhonda Shrum]

I see that Tarek and Christina's seminar is coming to my town. I know they aren't there, I know it's just a way to get you to buy a $2k course and then even pricier courses...I have no intention of buying anything. My question is, are these things worth going to for networking purposes? Are there vendor booths set up? Will I meet professionals from banks and real estate agencies, or is it literally a room that you're locked in for an hour?
