The point of a business trip is to conduct business. I've visited the Hyatt Regency several times over the last few years, and the thing I really like about this hotel is, it lets you get right down to business.
The rooms are spacious and nicely appointed. On my most recent visit, my room on a high floor offered a surprisingly interesting view of the commercial center of Reston. Room amenities were fine, although not exceptional. The bed was comfortable. Everything seemed very clean. I appreciated the extra electrical outlets built into the frame of the desk--a subtle touch that provided plenty of power for recharging those indispensable electronic devices.
The meeting rooms of the hotel are organized around a pleasing and airy atrium. The arrangement helps to relieve tedium when moving from one meeting to the next. Catering was efficient and pleasant; meals are above average for large meetings.
The ground floor restaurant, Market Street, is surprisingly good. There is sufficient space around the tables to promote quiet business discussion, and the wait staff is right there when you need them. The hotel's front desk staffers are also cheerful and efficient.
The Hyatt Regency is not particularly convenient if you are traveling to and from Washington--the city is a 45 minute cab ride away, and it will cost you about $75 each way. However, once you arrive, you will enjoy the environment of a hotel that truly understands how to help businesspeople get down to business.
