My hubs & I are planning to go to Washington DC this summer! We don't have any kids yet & thought DC might be fun since I have never been before. From the midwest & am not familiar with the area at all, but am hoping to use those Cat 1-4 certificates that are accumulating. Will be flying in from Chicago, but will probably have a rental, so driving is fine. I saw some bad reviews on the Fairfield that is in DC and no others that are cat 4 or less. Any other suggestions in the general area that are nice?
