If the trip you take is about photography, dedicate yourself to photography. If the trip is to enjoy new sights and cultures with family or friends, dedicate yourself to family and friends.
Your camera cannot distinguish subject matter from non subject matter. Therefore it is up to you to record only that which is important to the photo. The easiest way is to get closer and fill the frame with just the subject. Think of the camera viewer as a canvas. Put on it only that which is important. Leave out the cans, butts, passing waiters, gawking tourists, parking lots, UFOs etc. Get CLOSER.
