We went with a ROTC school trip March 2012, as a parent chaperone. Staying at the Hyatt Arlington was not a good choice for this trip, there are better places in Washington.
Good: 1. Very close to the Rosslyn metro. Within a block from the CVS and a grocery store. Some of the front desk staff (specifically the men that stocks the small shop and Robert) are outstandingly helpful. Elevators are reasonably fast. Elevator requires a key card after 8pm. Front staff was helpful when we required copies and had to move some kids around. Neighborhood seems fairly safe. Rooms are clean, has a connector for audio/video by the TV.
Mediocre: No pool, but oh well, parking is tight, anything over a small SUV would be almost impossible to park. Parking is 20 dollars a day.
Linen is pedestrian. pillows are ok, but not great, at least there are more than two. View is of other buildings and the street, which is better than I usually get (I usually get the Air conditioner view)
When I asked the front desk about area restaurants, they did not have a recommendation except that they had heard that they were OK.
Bad: Internet service is $9.95 a day for four devices. Why?
Walls are thin, but I noticed that I could hear the room clearly next to us through the heating ductwork. Our kids were not being loud.
We requested a breakfast consisting of an all american breakfast, but apparently there was a miscommunication. Breakfast was $16 dollars (I think we ended up paying $14) for liquid eggs out of a carton, Cereal, cold potatoes, warm juice, bread (toasters were in a different room) and the smallest cereal bowls I have seen. The next day they added bacon. Not a good deal, not hot, and the only person we had doing service was one lady who did her best to keep the room straight. We never saw any other kitchen staff, and other hotel guests just went and helped themselves to our breakfast because it was set out in a public hallway.
We did have a complaint on our kids for slamming doors, we weren't aware that we didn't have the entire floor, so to the man in 505, sorry about that. For the most part, our kids are very well behaved, but when they were waiting for our bus, (in Air Force JROTC uniform) we did get the stinkeye from another hotel guest. Our kids attempted to be polite to her, but she was pretty nasty to them.
WI FI is NOT FREE....let me reiterate this....WIFI is NOT FREE. Neither is anything else. Washington is expensive anyway, but everything was overpriced at the hyatt. $5 for a bottle of water should have gold flakes in it, and be served by a butler on a gold plate.
Parking for our bus in away from the hotel in what seemed like a sketchy area, but nobody messed with it.
Would I stay here if it wasn't a school trip....No. The kids weren't impressed, and neither was I.
