Scotland or Yorkshire?

This is our dilemma these days: my wife and I want to plan our summer holidays and we don't know where to go. We are very tempted to visit either Scotland, more particularly but not certainly Edinburgh, or Yorkshire, probably in York. Not the new one, the old one. She has been to York, but never to Scotland. I have been to Scotland, once, when I was a child. I have been longing for it since then. This is where my ancestors come from. A journey to Scotland has been long overdue. But then, there is Yorkshire, one of the most picturesque region of England and a that I have been curious about for quite a long while. And I know of a couple of places in York I already want to visit. So we are having this terrible dilemma.
