Hotwire offering 4* Foggy Bottom at $89 for 3/15-3/18 (3 days), and deduced it was the Westin Georgetown. Bid $80 on Priceline for 4* Foggy Bottom and got it (first bid -- oops!). Then offered two more days (3/13-3/18) and got them too. Sometimes pays to wait until the last minute? Good prices for 3/15-3-18 were very hard to find earlier.
