I live in the DC area (just south of The Mixing Bowl), BIL lives in Cockeysville so I'm familier with the route. As you can see by my sig pic I'm pulling a load. It seems that for whatever reason I can't wait to get to Disney. We usually leave around noon on a Saturday and drive to the Brunswick, GA Flying J (stopping at the Carmel Church, VA and Latta, SC Flying Js along the way) to overnight. We usually pull in around 10pm. We're on the road pretty early Sunday morning getting to The Fort around 11am. Coming home is something similar. We leave The Fort by 11am but may go to DTD for a couple of hours before finally leaving. DW really has to push me to leave. I drive until we get to the Kenly, NC Flying J (stopping at the others) to overnight. I don't really pay attention to what time we get home as I'm already planning our next trip to The Fort. Total driving time is about 16 hours, yours may be closer to 18 hours. I drive 60-63 mph (best fuel economy) when towing. I've only driven through once and it took 13 hours but then I wasn't towing and keeping it just this side of light speed.
