We are in CT. When we drive anywhere 'down south' we always go the route that I assume your husband is suggesting rather than down I95. If I remember correctly, we take 84 out of CT toward Newburg NY, the go down thru PA westward thru PA, then into MD, WV, VA and south. Eventually we get on 95 somewhere in SC, the go down 95 the rest of the way.
The good thing about heading that wasy is that you totally avoid the hassles of traffic in NJ, Philadelphia, Washington, Baltimore, etc.
