Try dry ice or blocked ice. We swing by Safeway on the way out and grab 5lbs to throw in our small fridge to keep it cold while traveling. We keep our drinks and lunch in it while traveling for quick access. Once we are at our destination, we leave it out to evaporate...of course, keep away from the kids...
I think you will find a chest freezer will stay at/near temperature for about 12 hours if full....

Depending on how long the stay. I think the dry ice idea is better also. We used it back in our tent days and it worked good.
