bk - I'm glad QuikBook.com worked out for you. I've walked by the Chelsea Wyndham a couple of times, looks like a good hotel. I also believe that all the hotels available on QuikBook.com have been "approved" by the QuikBook's staff - and if any customer happens to have a problem with the hotel, then the customer can report any problems back to QuikBook.
*You can also follow them on Twitter: @QuikBook -So that you can get advance notice of any upcoming sales.
**They also handle hotels in other cities, and, after just taking a glance at the site, if anyone has been thinking of planning a trip to DC this summer... -There's a $67(!!!)/weekend night special for the Latham in Georgetown right now!
