Personally, I have heard from a couple of people whose company popped for the tab for them to go and they told me that for what they learned at the conference, versus the total cost of going (hotel, meals, airfare. conference) they said that it was overrated. Alot of it they already knew. But, on the good side, that they had a good time in Vegas on the company dime anyway. :-) I asked them "Well, would you have popped for it yourself?" and the resounding reply from all of them was "No". I have never been myself. This is only what i have heard from people who have been. :-D
