I wrote this a few years back, while working on our Northern European Cruise Ports guidebook, somewhere in the churning North Sea. As I write this, my cruise ship is rocking violently to and fro. In a bit of delicious serendipity, the afternoon’s scheduled entertainment was — I am not making this up — a troupe of Chinese acrobats. Wise move, Chinese acrobats. And if I’m lucky, maybe they’ll reschedule those Chinese acrobats.
