Arriving into Amsterdam from Florida I had the advantage of my time zone. So I walked around the central section of the city late into the night.
At that time I was doing some software work for a client. These days I do most of that type of work remote, so I felt it unnecessary to mention that I was out of the country. From my hotel, I could take meetings as if I was sitting at home. Then, when done, I would step outside and explore the city.
What brought me there in the first place was a photo exhibit I was participating in just outside the city. I was able to attend the exhibition, explore the city and, for all intents and purposes, continue helping my client as though I was sitting right at home. It was a new experience that worked out well on all fronts.
