We took an "Arctic Islands Expedition" trip on FRAM, sailing from Tromso, Norway on May 13, 2016 and finished at Reykyavik, Iceland on May 22nd. In between we had three Zodiac landings (Bear Island, Hornsund, and Jan Mayan) as well as three port dockings at Ny Alesund, Longyearbyen, and Isofordur, the first two were in Svalbard and the third was in Iceland.
The scenery was excellent, this goes without saying. There were a bit more than 200 passengers, about 40% are Germans, 30% Norwegians, 25% British, and 10% Americans. Most passengers are quite experienced.
In particular, in preparing for the tour I read numerous reviews on CruiseCritic, and noticed that several of them had rather harsh reviews on the ship. We are quite satisfied with the ship and with our cabin (cabin 346, category N, about 140 sq ft and fitted for handicapped access). In comparing with many other cruises we have taken on other cruise lines, we did not find anything close to excessive nickeling-and-diming. Water, coffee, and tea in the dining room are freely available, and good hot cocoa is available round the clock outside the dining room. The food is plentiful - it does become monotonous after a few days but nobody comes abroad for Norwegian cuisine anyhow. All services, from dining staff to expedition team members, are at least functional.
