Good casino design pays off:
As conceived by Wynn and Thomas, the Bellagio’s casino represented a $1.6-billion bet on human psychology. The gamble paid oﬀ: the Bellagio generated the largest proﬁts for a single property in Las Vegas history. And this income wasn’t a by-product of scale—the Bellagio was less than half the size of the MGM Grand—but a direct result of the way that Wynn’s guests spent money. Per guest room, the resort generated four times as much revenue as the Las Vegas average.
Bad risk analysis, on the other hand, doesn't.
