I actually don't really have a cancellation policy, being an extremely small company/just myself. The exception to this is in rare circumstances of extreme weather - something along the lines of heavy freezing rain where travel will become too dangerous. Cloudy nights are hard, of course, but this is out of our control unfortunately. And the thing is, if we cancel by 20:00 and see the skies clear by 1am - we're going to feel collectively pretty awful. Often a breakup of cloud can lead to spectacular viewing and photography opportunities when you see the aurora tower over or through scattered cloud. It's a whole new perspective to something so grand and otherworldly.
