I agree that the hotel prices definitely drive people out, but also the general logistics problems, and things to do that aren't a conference are really silly in San Francisco compared to holding it in other more tourist-focused areas like Las Vegas. Las Vegas is capable of holding simultaneous high headcount events, and has the infrastructure to get a large number of tourists around without even batting an eye.

I'd be interested to hear other people's experiences but it feels like most conferences in San Francisco would start to become miserable in hotel price and commuting for people coming from out of town once you start getting to 20,000 or more people.
