I am going on an Antarctic Cruise with Heritage Expeditions From Bluff, NZ in Jan 2014. I was wondering what clothing and other items to pack as we are visiting a lot of subantarctic islands such as Macquarie along the way as well as the Ross Ice Shelf. These islands will have vegetation on them, not just ice, so there will be quite a variation in temperature over the duration of the 29 day cruise. Has anyone been on a similar cruise? How many of each item of clothing did you need to pack? Any hints ofr suggestions please.
