Re defrosting turkey. What are defrost times if ambient temp is oc to 5c? Would have thought turkey is OK in box if not in a warm Dandy but you are welcome to the freezer. (Not just idle conjecture many moons ago did intermediate food hygiene would have thought it's premature thawing is the least of your issues.) Other than for ice cubes or if anyone has a frozen desert desire I wouldn't have bothered with a cooler for other food items.
To confirm I will not be there Christmas day. Early leave Christmas Day return Boxing Day post hangover.
I'd counted the numbers and thought the maximum at any time were 10/12 dependent on Terry.
