100% agree with this. Using one example, experiencing Berlin in your early 20s (broke, energetic, careless, and seeing much of the world for the first time), late 20s/early 30s (ideally with a little bit more cash but in the prime of your "scene-ster" days), and then in your 40s or older (different appreciation on life, potentially with kids) are all very different. To each their own though - no such thing as a bad travel experience if you come back in one piece!
