When our evening flight to Los Angeles was cancelled, we re-booked an early morning flight out of Dulles Airport. We decided to stay the night before so we wouldn't have to battle traffic in the morning.
Reservations was easy and we were pleasantly surprised to find a very new and modern hotel. Of course, the cookie we received upon check-in almost made up for the cancelled flight. Service was outstanding and the bed was terrific.
We are Hilton Gold and were placed on the Concierge floor. One suggestion would be to have breafast open earlier thatn 6 a.m. There are people who need to leave the hotel by 6:30.
Even though it's a bit out of the way from Dulles (about a 10 minute ride) it is well worth it.
