Even if you crap out in its casino, Stratosphere Corporation hopes you'll still enjoy the view. The company's Stratosphere Tower, Casino & Hotel in Las Vegas is the tallest free-standing observation tower in the US at 1,149 ft. It features a revolving restaurant, observation decks, and a roller coaster that wraps around the top. More grounded is the firm's hotel, with some 2,400 rooms, an 80,000-sq.-ft. casino, a Broadway showroom, and a retail center with shops and fast-food outlets. Located slightly off the beaten path, the hotel offers a nightly evening shuttle service to the center of the Las Vegas Strip. Whitehall Street Real Estate Fund, an affiliate of The Goldman Sachs Group, owns the Stratosphere.
