Long a mainstay on the Norwegian coast, the 500-passenger MS Midnatsol (or Midnight Sun) has ventured out to even farther-flung shores. Starting the latter part of 2016, the Hurtigruten ship will be deployed in Antarctica and the Chilean fjords. This once-sleepy ship will be dialing up the activities, hosting frequent lectures and shuttling passengers on landings with the guidance of an expedition team. She'll be retaining her nature-centric focus and casual, do-as-you-please ambience though, and the programming will be active but not overly vigorous.
