We are heading out in February next year but starting to book excursions now. Will book a Northern Lights tour for the first evening so can reschedule if the weather is against us, but there are bus tour options or cruise/yacht options - which would be best? Just me and my 8yo son so he will likely sleep through parts of it too and the yacht looks a lot more comfortable for that. But are the chances of seeing the lights better at sea or on the land?
