As a frequent traveller for business as well as leisure, I have stayed at the Crowne Plaza (Dulles location) on several trips. It is a great location and is quiet and clean. I especially appreciate the staff who are friendly and are sensitive to the needs of frequent travellers. Wayne Thompson, the Room Manager, goes out of his way to remember guests and ensure their satisfaction. There are numerous hotels around this location, but I find myself returning to this hotel repeatedly because of the service and the fact that know I will get a good night's sleep.
