 The Union Station Marriott Hotel in St. Louis is now the St. Louis Union Station Hotel – a DoubleTree by Hilton. Built as a train station in 1894, the historic 539-room property will undergo a $13 million, four-year improvement project, which will include upgrades to its Grand Hall, once the staging and gathering areas in the train station and complete with original frescos, mosaics and art-glass windows. The AAA four-diamond property has nearly 60,000 square feet of function space.
