SirMoby, from my point of view, the Miami show has many times more value than the vegas show does. In Miami, everyone is close at hand, people always end up back at the show hotel, and generally people can be found, met with, and talked to. I honestly saw more "power" sitting around a poker table one evening in Miami than I did in the entire time in Vegas 2005.
I had a hard time justifying $4k for a few days in Vegas this year, and besides the fact that I am not happy to have missed spending time with some of my friends, I really didn't miss anything, and I feel I am up $4k as a result!
