If you're on the trip of a lifetime, chances are you will A) be taking lots of photos, and B) will be away for more than a couple of days. If the worst happens, and your camera is stolen, or your memory card corrupts, you will still have all your memories intact if you have taken the time to backup your photos as you go.
Not everyone has the luxury of taking a week to scout a new location for potential photographs and best viewpoints. (In fact, does anyone who isn't a professional location scout?)
But with Google maps and a couple of apps, you can plan a photography trip so that as far as humanly possible, you stand the best chance of getting the best shots.
