We stayed at the Westin in Tyson's Corner in September for our anniversary and we loved it! This was our 2nd stay here. I love this hotel because we get to bring our mini schnauzer with us. He is diabetic and we needed to store his insulin in a refrigerator. The hotel service came in and installed a mini frig in our room at no additional cost. Our first stay here - our dog had a big fluffy pillow to sleep on. In our 2nd stay - he did not :(. We inquired - but the hotel had all pillows occupied in other rooms. The room service is "excellent" - always accommadating to our needs. The restuarant in the hotel is "excellent" as well. We will be staying here again on our next anniversary! :) This hotel has free parking, a huge mall within 5 minute driving distance, just off I-270 for anyone taking a trip down I-270.
