BTW, the fridges at values are really small. Think college dorm type. Can fit about 6 water bottles in there.
What we did was stop at
Walmart's and buy a $18 cooler , fairly large one with wheels. Got ice each night, and kept everything in there. At the end of the trip, we left it in the room. It was still cheaper than spending $10 a day on the fridge and held lots more.
