The ships are 'working ships' and can be considered expedition ships rather than ordinary cruise ships.
In total there are more than 35 stops during the voyage - the majority of stops are for 15 to 30 minutes - only the stops in Ålesund, Tronheim, Bodø, Tromsø and Honningsvåg are more that 3 hours.
Some noise and vibration can be expected when docking and when loading of goods . Some of those stops are during night time, so depending on the location of the cabin there might be some noise when loading / unloading goods.
