Haha I totally feel you! I often walk the route twice. First to look around and then to take photos. But I also notice that I come back with fewer and fewer photos.

There are studies claiming that taking photographs actually intensifies the experience during a holiday trip. Researchers from Yale, for example, sent a test group on a bus tour through Philadelphia, half of whom took photos and the other half did not take photographs. Eye tracking showed that the group taking photographs experienced the trip more consciously through positive visual stimuli. The photographers also looked back on the trip with more pleasure afterwards than their non-photographing fellow travelers.

(The Yale researchers also established the opposite: people who create images of something unpleasant, such as a traffic accident, experience the event more intensely and retain a negative feeling about it for longer).

Last spring we made a lovely tour through Italy. It is indeed and remains a struggle. What do you photograph and what not. When I photograph with my camera, I of course want to make the "perfect" picture. That takes time and you don't want to inconvenience your travelling partner by spending endless amounts of time on it. Even if it is just waiting until those hordes of tourists have left the frame. But sometimes you can get the best of both worlds.
We were in the Basilica of Saint Francis in Assisi. Everything there is to see has been perfectly captured in stacks of books. No need to do that yourself all over again. So, the camera didn't come along. But, suddenly, out of nowhere, a magnificent song was started there by, as it turned out later, a group of students from California. This moved me and I wanted to hold on to the moment. So I took out my phone and took photos (snapshots). From a photographic point of view, they were unsharp pictures with visitors disturbing the image. But, what I wanted to hold on to had succeeded. So much so that I recently used one of those photos in a presentation about music and youth.
