Columbia Place, which is phase 2 of the Marriott Marquis project, entails two new Marriott hotels in the heart of downtown D.C. – a 357-room Courtyard and a 147-room Residence Inn. The hotels will be built adjacent to the existing Marriott Marquis, creating a true hotel complex for the Walter E. Washington Convention Center that will include more than 1,600 rooms across the three hotels for Convention Center event guests.
