The Crowne Plaza at Union Station in Indianapolis is built in the city's former train station, America's 1st Union Station. The Grand Hall is marked with distinctive arches, columns and terrazzo floors and features a stained-glass barrel ceiling along with two identical 20-foot leaded stained glass wheel windows. While most guests stay in traditional rooms, the hotel does offer the opportunity to spend the night in a Pullman train car. (Crowne Plaza at Union Station)
