I had a reservation at the Marriott Courtyard on R St. in South Boston that included breakfast since Courtyards don't have breakfast for Platinums, et al. When I arrived at the hotel the desk associate noticed that I had a breakfast included reservation. She informed me that this Courtyard has free breakfast for Platinums and changed my reservation to void the breakfast rate and gave me a lower price for the night.
The hotel itself was quite nice with an older, but very functional layout. Service was great at every turn and I would recommend this property when in the area.
