Keep in mind that there are a whole host of things to do besides drink anywhere. Our alcoholic minds just tell us that all people do on vacation is drink, but in reality they don't. You are actually surrounded by alcohol right now, we all are. It might not be in your hand or immediately available in your home, but it could be in a very short period of time.
Plan out your day to take advantage of the weather, outdoors, food, shopping, sightseeing, whatever else there is to offer. And while you are doing so, notice how many people are NOT drinking....you'll be pleasantly surprised to see that they are the majority.
