At current rates your maximum bid price is not realistic, as is evidenced by your rejected bid up to that level.
I'm not sure what is happening in the area over these dates, but even the 3* Comfort Inn Pentagon City which is in this zone is selling for $224/nite (making your maximum bid only a third of prevailing rates)
Do you specifically need to be in Arlington or were you looking to stay outside of 'downtown' which is even more expensive?
If you're ultimately objective is to visit DC how far outside of the city are you willing to stay, how high are you willing to go, and/or how low of a star rating are you wiling to accept?
There is this offer from HOTWIRE:
3* Tysons Corner for $58.00
==> not really sure what it is, maybe the Courtyard Tysons Corner, but no matter what it proves to be it does have a good 4.0/5.0 TA rating and is the most reasonably priced property i see in the area, should this work for your needs
