We have four, and we struggled this holiday (first camping holiday), borrowing some from the lovely campsite owner
someone has offered me some free; but I don't want to take more than I need
We usually picnic during the day, and keep milk in the tent. Also I don't know how many campsite owners are happy with you freezing - don't want to be the annoying bird with the freezer full of damn blocks
please suggest a sensible number for a chronic overpacker
