If the allowance is so small, what is the cost of bags of frozen ice then? This in combination with the cooler that other posts have mentioned would be really effective. Otherwise you could buy the freezer blocks to keep the food cold and recharge them at the various hotel freezers that you will be at - though I think most hotels only have fridges and not freezers.
