The National Sheraton was a very good deal. We had a little trouble getting a shuttle at Reagan/National. But, once we got to the hotel it was great. Athough, they charge to park, we did not rent a car and was spared the expense. We used the shuttle to go to dinner. The driver went out of his way to take us to the restuarant and then came back to pick us up. It was a great room and all the staff were vey accomadating.
