took a big esky with dry ice as a layer on the bottom, covered with newspaper then our stuff and a couple of bags of ice spread between the stuff. the dry ice kept the 'normal' ice frozen for a week. when we left, after a week, I still had some frozen stuff in the esky. yep, we took two so we managed to move stuff around, almost like a fridge and freezer set up. dry ice seems a bit difficult to get, but i would look at doing it that way again, if we were in for a long stay.
