I found that the rest of the family and me have different styles of planning travel iternaries.
When I spent an extra week around Germany after my study abroad, and for the weekend trips, I compiled a list of the places I would like to go beforehand, and adjusted the plan based on the actual visit time. For example, when I was in Berlin, I left the Berlin Wall Memorial and finished lunch before 12:30 (I expected to be 13:00-13:30), so I pushed the only remaining sight (German Museum of Technology) ahead by 1 hour (14:30 -> 13:30), and used the rest of the time before dinner to see the Brandenburg Gate, which I planned for the next day. I added in the East Side Gallery because of this for a better utilization of my 48-hour tourist pass.
But my family didn't have an exact iternary when we get to each city during family trips. They literally planned everything on the dot and decided whether to use the pass based on the lowest possible transport and admission cost, which made their approach very relaxed.
What is your approach when it comes to this?
