Thanks BlissWorld. Will look into the Westin Arlington.
I'm not an SPG anything, just your basic level points earner, as I usually stay elsewhere when I'm in DC *gasp!* So this is a brand new predicament for me. Wow...a $99/night Ambassador Suite? How does one score that? I'd go for shoddy service if any DC suite was $99/night. Ok. Maybe that's going too far...
