Do they still have the water park over by the Sahara? I was told the showgirls like to go there to cool off.
I don't get the whole high end bar stuff... not sure what makes a shot of grey goose worth $50 but whatever floats your boat.
I would much rather see Bryce/Zion if time permits YMMV.
Most of the big properties on the strip have some kind of free entertainment... the water show, the volcano, the pirate ship, the downtoun experience (light show), etc.
