Keep your freezers full, even if it means filling them with jugs of frozen water. Full freezers recover quicker after doors are opened and shut.

Editor's Note: This is true. The folks over at Newton (Ask a Scientist) concur. Here's a recent answer to a question on this topic.
The thermal mass of the food and especially water frozen in the freezer retains the cold when the door opens and the cold air is displaced by warm room air. If air is the only thing in there, it gets warm fast.Source: Newton: Ask a Scientist

This is true of your refrigerator too. I have a second refrigerator in the basement and on the rare occassion it starts to become empty, I fill it with unopened jars from the basement shelves. And this time of year it's always handy to have extra cold drinks ready since we go through them so fast.
The space useage in our small freezer fluctuates so frozen jugs of water often had to be removed for foods making a new problem of wet jugs as they thaw for reuse later. I solved this problem once and for all by putting packing peanuts or shredded paper in plastic bags from the grocery store and tying the tops shut. We can use as many little bags as needed at a given time. They are flexible and conform to spaces far better than stiff jugs. We can easily remove some and pop them into a paper grocery bag to await use later. This has proven far more flexible for us and totally eliminated the mess. Also there was another problem with the jugs which would develop a leak after several cycles of freezing/thawing.
Goodness! I can't imagine having to switch bags of water or styrofoam or whatnot. The freezers at our place are always full! We don't formally do any "bulk" or "once-a-month cooking," [though we keep planning to] but my sister and father are good at catching sales and buying meats and such items then freezing them. We even freeze bread.
Perhaps those with semi-empty freezers can look more carefully into the OAMC sites abounding the Internet :)
