Thank you so much for your responses.
I appreciate the advice to take the eastern route. Playing at Blackpool or seeing the Lake District at Oxenholme do seem appealing, but I don't think it can be done and still get to Glasgow in the early evening. So, I will check into Durham and others mentioned in the east.
We will be seeing Edinburgh just as soon as we leave our friends in Glasgow and we anticipated stopping in York on our return trip to London.
Cheers.
