My sister and I just sailed on the Star, 10 day Iceland/Greenland cruise, R/T from Reykjavik. (Djupivogur, Akureyri, Isafjordur, Nanoralik, Paamuit and Nuuk)
Four of the six ports were tender ports. We were able to visit all ports except for Djupivogur because it was really really windy. Tendering would not have been safe.
As mentioned in the post by @DMP609, Prima doesn't have tenders so that is why they are skipping Isafjordur until dock is completed.
The Star is smaller and if it is chilly/windy, indoor spaces can be crowded. We had a balcony and bought the Thermal Spa pass so we always had some place warm to relax. Some very brave souls did use the hot tubs and the pool!
We were able to find quiet places to read. We didn't see any shows but there was something new every night.
It is a beautiful part of the world!
