I cruised on Le Boreal as part of a chartered Abercrombie and Kent expedition including The Falkland Islands, South Georgia, and the Antarctic peninsula in Dec 14/Jan 15.
There are many reasons to select Le Boreal/A&K for this adventure:
* Itinerary: every other expedition in this category and with these stops is 20+ days. This was 17, and was certainly not too short. It hit all the highlights you want to see, and there were plenty of expeditions at each stop.
Smallest/standard double occupancy room. It was totally fine. I really liked this location close to the forward elevator
