If it were me and I had time for re-bidding, since I know that at least the Hyatt has availability and they have sold Priceline rooms in the past (with 686 rooms, they have a lot of beds to fill!) - I would start with a low-ball bid for 3.5* in Crystal City, probably $70-80 (if it were me I'd try 70 - I like to get rooms cheap!) and go higher bit by bit, but a more realistic bid might end up being 100-130, if they even bite. Arlington also has some nice hotels that sell Priceline rooms - I haven't checked availability, but it might be worth looking into (it seems like when I've looked into some of those hotels - they are a bit far from the nearest Metro [like up to a mile away], but then, the Hyatt Arlington is right on top of the Rosslyn station, so you might get really lucky!). And, yes, if you have an unsuccessful bid with Dupont Circle, you can add Crystal City, even lower your bid if you want (I would!), and re-bid right away without closing your browser - Priceline will prompt you and ask if you want to change something in your formula - you can re-bid right away if you either add another acceptable zone or add another (lower) star level. If you are unable to change either of those factors, i.e. you are set on a particular zone(s) and star level, then you have to wait 24 hours before re-bidding. Especially in a city like DC that has such a wonderful Metro - it can really pay to be flexible and consider zones that aren't right in the heart of the tourist meccas. A couple of summers ago we were hoping to be right down by the Mall, but ended up getting the Marriott Wardman Park (Dupont Circle - Woodley Park zone; 3.5 or 4*) for $80 or $85 and we were only a couple of blocks from the Zoo and literally right on top of a Metro station which got us down to the Mall in maybe 10 minutes (you can check schedules and figure travel times on the Metro website). You can search for successful bids in a particular zone by using the "Search" field at the bottom of the "Pricline - Washington DC" forum (just put in the zone name) - sometimes that makes the research a little easier. I hope some of this helps - I'm no expert, but I do love to get cheap (but nice!) rooms on Priceline, and I'm getting pretty good at it! Have fun in DC (btw - you should absolutely not miss the Newseum when you're there!!! look it up - it's fantastic!)!
