I used to commute Worcester to Washington every other week, I love the trip, but then I love both places. Jct 64 A1(M), Washington is around 4hrs from Worcester and within sight and sound of Beamish Morgan if you need any spares (not that you will).
It sounds like a great road trip. I've done the far north of Scotland quite a bit in my MG and its wonderful, unspoiled, unhurried place.
