It would have been neat if some one had suggested Las Vegas. There is alot to do there after the convention.
LasVegas Nevada. Las Vegas Tourism.

The problem with Vegas, of course, is the hotel cost (though the travel cost would probably be lower)...

Hmm, must have forgotten to hit submit as I had typed in a reply quite awhile ago.
There has been a bit of discussion for the last several years, since I have been involved (and maybe before that but I don't know), about having it in Las Vegas. So far though, no one since I have been involved, has submitted a bid.
Writing just off the top of my head without checking into it, I figure it may be possible to get decent guest room rates but conference room rates are likely to be prohibitive.
As with any potential location, it requires someone that wants their location to be "the" location to put together and submit a bid. If there is someone that really wants the Las Vegas location they could probably find a decent price point if they were dedicated enough to wanting it there to search for it.
