Catch I-90 to I-84 to I-81 all the way down to I-77 to I-26 to I-95 to I-4. We did this route 3 weeks ago and it was great compared to I-95 all the way. It had lots of signs, rest areas, and stops right off these routes for food and lodging. The traffic was minimal by comparison and virtually no big cities to contend with. We drove this route 22hrs straight from Hilton Head (after WDW of course) to Maine and it was great. We did I-95 all the way on 9/12 last year and it was the absolute worst 25 1/2 hours ever spent in a vehicle.
