Some good ideas, thanks
My brother-in-law, who is going, lived and taught at Oxford for a few years so I am hoping he will do the driving if we can't get somewhere by train.
+ 1 on the train. At least from London to Edinburgh. We broke up that leg of our journey with overnight stop in York. Nice town to stay in.
When I went to Europe I absolutely enjoyed riding the train. Ireland was the only country where we rented a car. It wasn't that big of a deal driving on the wrong side of the car/road outside of the big city.
I would have liked to have seen more of Scotland but it wasn't in the plans. Glasgow was the only other city we stayed at. Pass on that one.
Have fun and enjoy the sights.
