The Westin Tyson's Corner is a decent property- a fairly standard Westin that has recently been refurbished. Parking is very easy (self-service lot), and it is near the Beltway and 66. I'm fairly sure they do not have a club lounge, but there is a mini-Starbucks in the lobby which has the normal range of pastries, etc.. Nothing special about this property, but it gets the job done.
