Hub at Tucson, Arizona
No University of Arizona students might be persuaded to ever leave the roof at the Hub at Tucson. There's a rooftop infinity pool with hot tubs and pool and foosball tables, as well as a 22-foot LED outdoor TV and sand volleyball court surrounded by stadium seating to catch the action. Inside, there's a yoga studio, sauna, steam rooms and tanning beds. A note to parents on the website points out that bedroom doors are solid to minimize noise. Probably the noise coming from the volleyball court.
