The Hyatt is wonderful! It's in an excellent location if you're flying out of Dulles. The shuttle service runs every 30 minutes and the driver was polite and prompt. The room was comfortable and quiet, and all of the amenities were up-to-date. There is a business center to print boarding passes (for free!), and there is a wide variety of breakfast items in the morning. We were able to grab coffee and snacks prior to our 6 a.m. shuttle departure. The hotel is only 7 minutes from Dulles, and it's easy to access. There is a Sheetz convenience store next door, and that's an added plus!
