So...what do I compare this too as a benchmark?
Never having being to Vegas before it was difficult to say, I guess I'd mark it against a super sized hotel in one of the gulf states?
If so, falls down on that 'top 10%' in quality, fixtures and fittings compared against the best elsewhere. However it's very good, and the most opulent hotel I've stayed at in the US.
The casino is awesome and obviously can't be compared with anything else so that's a 5 star rating.
Overall, huge, sprawling, fun and decedent.
