Between this and the disgraceful treatment of Defcon attendees, Las Vegas is telling the IT world that they do not want our money and we are not welcome. Hopefully next year conference organisers can find different venues in another city where they will be welcomed rather than persecuted.
Could probably find plenty of places in Westchester County NY to host moderately-sized conferences, and it's still close enough to major transportation. Certainly cheaper than NYC and not beholden (as much) to labor unions. Beyond that there's Poughkeepsie or Kingston, although they're not so "pretty" to visit and function space is smaller and farther between. But even cheaper than Westchester.
