The incredible transformation of a once-crumbling mining town to a gambling hot spot will reach new heights with next week's opening of Ameristar Casinos' 33-story, $235 million hotel and spa. The Las Vegas-based company lifted the curtains on the tower Monday, revealing a five-star quality hotel replete with teardrop crystal chandeliers, a full-service men's and women's spa, a 60-foot-long rooftop pool, a 700-person event center and 15,000 square feet of meeting space.
