You can divide it by a) Putting Alexandria VA into https://www.google.com/maps b) Clicking 'Directions' and entering 'Seattle'. c) Looking at the route given and working out which places would be best to stop. You can easily zoom in and out . d) Using google to research suitable overnight stopping places in the area. Assuming you travel from Seattle to Alexandria (Virginia) primarily via the I-90, I-94, I-80 & I-76 I'd suggest stopping: 1. Somewhere east of Spokane 2. Somewhere in the vicinity of Bozeman 3. Somewhere in the vicinity of Medora (North Dakota) 4. Somewhere between Fergus Falls andSaint Cloud 5. Somewhere between Saint Cloud and Milwaukee 6. Somewhere between Milwaukee and Toledo (Ohio) 7. Somewhere between Toledo and Somerset (Pennsylvania) PA. Somerset PA is approx 180 miles from Alexandria VA.
