“It’s one of the most storied properties still open today.” “It was seen as a cut above other places and a little more intimate,” said David Schwartz, a gambling historian and former director of the Center for Gaming Research at the University of Nevada, Las Vegas. The high-rise Stardust opened the following year, costing $8.5 million. The Flamingo had been open for a decade, the Sahara for almost 15 years. When it opened with three stories and 300 rooms in 1957 at a cost of $15 million, it was described as the most expensive hotel-casino built in Las Vegas and dubbed the “Tiffany of the Strip.” The hotel has been operated in recent years as a DoubleTree by Hilton. It has two towers of 22 and 21 stories on a 35-acre (14-hectare) parcel at a Las Vegas Boulevard intersection with a major thoroughfare named for it. The Tropicana Las Vegas opened in April 1957.
