Long transit stops can be both the worst, and the best.

The worst = A three hour train station layover in a town I had no plan to visit, Bayonne (though the station was a picturesque old thing)

The best = Discovering that Bayonne is a great little Basque city, with beautiful, medieval, winding streets. And then a ska band playing in the cafe next to the station while I enjoyed my I’m-not-sure-what-kind-of-meat-that-was kebab wrap.
