The Hyatt House hotels in Sterling and Herndon can be had on the cheap too.
Hyatt Fair Lakes is near the Hyatt Place South for an easy 2 stay weekend, but even with the remodeled lobby/bar/restaurant, which are nice, I cannot recommend Fair Lakes based on the all around atrocious service and poor management follow up. Hyatt Place South on the other hand is a parking lot away from some good Vietnamese food
