My husband and I, both senior citizens, are flying into Dulles the evening of March 23. We do not want to rent a car so are looking for a nearby hotel, preferably with a complimentary shuttle, that has a tour desk where we could arrange day trips to Monticello, Mt. Vernon, etc. We will be meeting up with our daughter's family at the convention center Embassy Suites in Washington, DC, on March 28 and plan on "doing" Washington with them March 29 through April 1 and then flying home on April 2. Any suggestions as to where to stay or make day trip arrangements before we meet up with them would be very much appreciated!
