Our fridge stayed pretty cold last time we went. We filled gallon-size Ziploc bags with ice from home and threw them in the cooler over the frozen food. When we got to the CG, my wife put the bags in the freezer. 2 days later as we were packing up, she pulled them out of the freezer and they were frozen solid. And the fridge wasn't even on high.
