You have two ways to start your "vacation". The first is fully prepared - having stocked up on all necessities: candles, good books, deck of cards, bottles of wine, gallons of water, grill food, etc. Some people just like to be prepared, and you have to give them that.
The second way is to use items and food stocks that you have in your home, and use foot or pedal power to get the rest. Walk to the library on Saturday to get a good book. Stop by the grocery store, buy and carry what you'll need for the day on the way home. What, your nearest food store is 5 miles away? Dust of that bike and flexible cooler and head out! Or, see if there is a closer alternative that you could walk to. Local corner stores, butchers, specialty stores would love to have your business. You won't have asian pears, and imported organic soy oat grass bars (or what ever is your fancy) in the same place, but maybe you'll be surprised at what you can find in walking distance.
The point is not so much to create rules and turn this into a game as to slow down and really understand what would disappear along with cheap energy, and why it's important to move toward a truly sustainable society.
