When we stayed at POFQ, our fridge wasn't keeping anything that cool, and the freezer section let our Mickey Heads melt. So, we called the front desk and they said "Well, it's more like a cooler". I couldn't belive it, because I pretty much had the same fridge in my dorm room in college. Coincidentally, they had the temperature control knob removed. We had them come up and "adjust" it, but it was no better. So, I took a pair of my wife's $20 tweezers and turned the shaft where the knob is supposed to attach. Then it worked.
Lesson learned: Bring a pair of pliers next time you go.
This really doesn't address your question, but we got a good laugh out of it. And we still use the "It's more like a cooler" line until this day.
