This is a science cruise not a booze or casino cruise. The ship is well equipped for Southern Ocean sailing. Cabins are good and food excellent. The science crew offer landings, lectures and science experiments. Catering and hotel staff excellent.
It is strenuous. Don't go if you are not mobile and can't get in and out of ribs. There are no landing stages; your stepping onto ice, or sliding over the side of the ribs.
It can be cold so take several layers.
