Hi Isabell,
We're in Ottawa and have taken the 81-83-95 route through Washington many times. In 2005 though, we continued south on 81 past Harrisburg where we would normally cut over to Baltimore on 83 (and then south to Washington on 95). We went to Winchester, Virginia before heading east to 95, picking up the interstate north of Richmond. We left the house around 8 a.m. and arrived in Chester, VA (which is about 1/2 hour south of Richmond) at around 6 p.m. Our kids were 8 and 2.5 at the time. We'll be taking this route again.
On day 2 of driving, we left around 9 a.m. and stopped for a couple of hours of outlet shopping in Smithfield, North Carolina, and then drove to Savannah, Georgia, arriving around 6 p.m. We stayed in Savannah until Monday before driving to Orlando. We could have easily made it to Orlando on Day II, but we would have missed some of our favorite stops (Smithfield, Savannah, St. Augustine, Titusville [the best seafood/rock shrimp in Florida, IMO]).
It's about 24 hrs. of driving either way, but we plan on taking the 2005 route again this fall.
