Have You used Hotwire?

Stephanie and I are planning a trip to the DC area in may for The Whiteboard Sessions conference being put on by my friend Ben Arment. Can't wait for the time away and meeting some new friends out there!

Right now we're trying to line-up hotels and flights out there. Man this stuff is expensive. Stephanie wants to book now, I think if we wait long enough the rates on Hotwire.com will keep coming down. What is your experience with this? Now or later?

*If you have an frequent flyer miles you want to transfer let us know! We'd be happy to work out some compensation. :)
