It seems to me that one way to measure how much you enjoyed the place, city or country you traveled to, is to think about what you remember when you’re far away from it. If what comes to your mind is just a hotel room or a restaurant meal, probably that place hasn't impressed you much. But if you recall a scenic spot, a dreamy landscape or even just a certain sentiment, probably that trip meant something for you...
And sometimes even an insignificant, mundane scene can pop into your mind, filling it with a strong feeling. That happened to me when I remembered this train station in Tokyo... it brought back the feeling of being at the starting place for a new exploration...
