Cool food, etc. - when traveling in motels without a fridge

Unfortunately there is no heading "traveling" and I have not found a better category.

When I travel in the US, I mostly cook myself and have my food with me. When staying for example Unfortunately, in a motel without a refrigerator they spoil very quickly.

Therefore, I wrap my foods, which need to be refrigerated, waterproof in plastic bags (such as freezer bags) and hang them in the water of the flush box of the toilet flush.

Happy Holidays
