Yes, it was a long day…started in the dark and ended in the dark, LOL. I took the subway/tube to, I think St.Pancras station early in the morning, then got on the train to Edinburgh. I made sure I knew the time of the return train. Had a really nice day in Edinburgh, then took the train back. Arrived in London about 11pm, but lots of people around and felt safe. Even the walk from the tube station to my hotel at that time felt fine. I’m glad I did it.
