Scenario

[IB1]

One week should be manageable for virtually anyone on this site who has given it just a little thought, water being the main problem but getting a weeks worth of drinking water in stock should be the first thing on any new preppers to-do list. Disposal of human waste would probably cause the biggest problem, short term answer would be burying it in the garden, longer term would be a compost loo but as we are only talking about a week here then burying will do. Other than that, go into full grey man mode and act as if I am as confused and short of food, water, and heat as everyone else

It all depends on where you live as well, 2 days without power in the middle of a large city could cause total mayhem, a week without power in the countryside could be a problem but not a major one.
