We (family of 4) are going on an Iceland and Greenland cruise later this year - first time cruising. We have several days on the boat so keen to at least get off when we dock. Trying to work out though if the 'trips' here are worth it. The cruise provided ones are extortionate but even private ones are still pricey - at least £150pp for a few hours. Having never been on a cruise or to this part of the world I'm trying to decide if at least one is a must do (to see the unusual landscape etc) and if there are any other provider options we have not considered - Help!
