I find myself in the same position all the time, granted i dont travel that much and that too mostly for pleasure, but when you can get in hilton type hotel using hotwire for 80.00 when their website says 130.00, well i think its worth it. One thing though, recently i found that miles4mart gives you points for every purchase through most of travel companies, and these points are converted to mile at 1:1, not a bad deal i think.
