Attentive staff, Tall Ships are awesome
We arrived on June 15, 2012 which coincided with the Sailabration in the Inner Harbor, Baltimore (see more at starspangled200 dot com). The Sheraton was located so close we could easily walk to the ships and sights of the harbor. While the folks at valet were a bit confused, the front desk staff straightened that out right away and we had a wonderful time. Our praise for the Sheraton could not be higher. In fact we now always choose Sheratons and Westins (Starwood properties) over competing chains such as Hiltons and others. We value service, safety, and security quite highly, and find that the Sheraton and Westin hotels consistently deliver. Why take a chance when you know what you will get when staying at a lovely Sheraton or Westin? 
We even received a nice follow up note from Kathleen, the Director of Operations, after our stay.
