The lowest I ever got it was for $49 when US Airways had an agreement with Starwoods 3 years ago to email advertise and hyperlink specifically with SPG. That was good. Also got it for $59 last year. Both times, I though the big King room on the high floor was excellent even as a Starwoods green.
Then I found the DT Tysons with my HHonors GLD and also had a great stay. If the DT had rooms like Sheraton Tysons and Sheraton Tysons had the *huge* amount of benefits DT gave me, then it would be an ideal hotel. So where's the 2 mile skywalk bridge linking the two?
