For a recent trip to Hawaii, we had better flight options out of Dulles, which required a very early flight. In those cases, we always like to stay at a nearby hotel to be close to the airport. Our travel agent suggested a park-n-fly option with Marriott, and it was a home run. For one price, we got the hotel room for one night, and parked in their lot for the duration of our stay. Then their shuttle took us to the airport terminal, and picked us up on return. As my grandson says, easy-peezy. Saved us a bunch of money on the ridiculous Dulles parking, and the hotel was very nice. It's obviously very older, but seems to have been maintained well. All the staff were very friendly, and we slept comfortably the night before our flight. We will definitely do this again on our next adventure.

The only reason to stay at the Dulles airport Marriott is for the convenience of being right at the airport. Based on my experience, you certainly don’t stay for the hotel. It is tired and worn out with tired and worn out furnishings and musty smells. This was my first stay at a Marriott and I thought it would be akin to a Hilton. It was more like a Days Inn budget experience. Unless you really want to be right at the airport, stay a few miles away at a mid level hotel that has a shuttle and save yourself half the price of the Marriott.

Nice hotel. Some rooms are so far away, you'll feel like you walked back to IAD. Room thermostat reverts to 70 degrees after a while. If you like other than 70, don't stay here.

We reserved ten rooms, send the credit card authorization in advance, sent a room list in advance. Staff member who checked us in was nevertheless extremely confused, giving us two sets of keys for the same room, another set that didn't open the indicated room, an additional room that we hadn't reserved, etc. We arrived at 1130 pm, and it took until past 1 am to straighten all this out, partly because he was the only staff member at the desk and many other folks were trying to check in (the line moved very slowly). No acknowledgment of Ambassador status at all, no real greeting, no apologies. I would be annoyed if this happened at a Towne Place Suites or somesuch, but a Westin that's this understaffed (qualitatively ad quantitatively). it's really alarming. I expect I will also have to spend some time and effort getting someone to correct our receipts.

Stayed one night on our way home from Europe. The room and lobby and hallways are definitely in need of renovation. Toilet did not flush well, room seemed really old as did the hallway.Restaurants as mentioned —there is only one. Had both dinner and breakfast and the servers were very very nice, especially the lovely Asian woman at dinner.Instructions for where to meet the shuttle at the airport were vague so I had to call and keep them on the line while I figured it out. Check in (we are Marriott timeshare owners) was confusing and hard to communicate that we are platinum—lounge food not impressive.
