I have no idea how bidding so far in advance would affect things, but Priceline wins for a 4-star hotel in Dupont Circle area are often Marriott Wardman Park or the Renaissance Mayflower. Less often but definitely possible include Washington Hilton, Omni Shoreham, Kimpton Palomar and The Dupont Circle Hotel. Edit: oops, you were specifically inquiring about Hotwire. Of course that isn't strictly "bidding," and you should be able to determine the exact hotel with the proper sleuthing. It's worth noting that the Renaissance Mayflower is in the White House zone on Hotwire, not the Dupont Circle zone.
