Get the picture? Prepare well. Best to provision in the last town you pass through instead of leave it to the last minute and pay middle of nowhere gotcha prices. It is a good idea to carry some cash too. Fact is, if the hydro goes out, credit cards cannot be used. It doesn't happen often, but it does happen. This can be particularly important if you have children.
It may be a little more fuss than you are used to, but the payoff is worth it. You will get to enjoy a beautiful place without the consumer hassle. And I won't have to hear the sad stories...I can't do anything about your luck with that.
