I've pretty much seen the sights that interest me.
The climate is miserable.
The food, while often very good, is too expensive and not that much better than what I can source locally: I am not a gourmet.
Other than Cirque performances the entertainment is not interesting to me, and Cirque travels to stumptown on occasion; we have some decent comedy clubs as well.
I don't drink, so the availability of free alcohol while gambling means nothing to me.
I now have casino gambling opportunities available locally comparable to those in sin city.
Strip casinos now charge resort fees and parking fees.
Airfare and rental car expenses are always a factor.
So really, why bother?
Been there, done it.
But the city's history still fascinates me, as does its continuing evolution as America's glory hole.
