We are looking for a nice place to breakup a train journey between Paris and Penrith next May. We do not wish to stay overnight in London after arriving there on the Eurostar. Instead we want to continue north, preferably from St. Pancras or Kings Cross station, to a small town with easy train access, a nice small hotel, hopefully some historic character, and a nice place to walk. I have come up with Lincoln (Bill Bryson likes it) and Stamford. I know Lincoln offers a beautiful cathedral and a Norman castle, but in the time we have there (late afternoon and next morning until 11) we will not have time to tour the castle or do the roof or tower tour at the cathedral---we can only visit the interior floor area. Stamford seems to offer a well-preserved town and nice walking, so I am leaning toward that.
Any advice or comments? Thank you.
