When I was in Norway a few years ago, for half the time I was on a postal boat from Bergen to Kirkenes. This was very interesting because it stopped at EVERY port along the coast, delivering all sorts of things. Also, during summer it's moreorless light all the time, so you would dock (and I was lucky enough to have a cabin on the port side) at some ridiculous hour and there'd be all sorts of interesting things going on. Norway benefits from having the Northernmost bit of continental Europe in it (Nordkapp), and so there, and at this time of year (winter/dark) would probably be the best spot to see the Northern Lights...

Marc!
