I did this cruise Aug 2019. The scenery is beautiful and you if you love to photograph nature you will really enjoy. Take an excursion that will take you out to the ice caps/sheets. Along the way you will see lots of iceberg. I was able to get an excursion in Qaqortoo from an independent operator and walked on the ice cap. The Greenland ports are mostly fishing villages and in most cases the ship passengers will out number the residents.
If your phone has wifi calling capabilities you can use it and the calls and texts are free. That's how I'm making/receiving calls & texts. Tanya
