Mirage

The Mirage was the most expensive hotel-casino in history, with a construction cost of US$630 million. The hotel's distinctive gold windows get their color from actual gold dust used in the tinting process. It was reported that the resort would have to bring in a million dollars a day to pay off a 7-year construction loan. But in fact The Mirage did so well, the loan was paid off in just 18 months.
