I don't take more than a few pictures on vacation anymore. Ive learned I can enjoy the experience more if I'm not worried about trying to take pics of everything. Better yet, my memories of the experience are better than the pictures I used to take. Giving up "must capture this moment" mentality allows me to be present in the moment. It is very liberating.
I'm actually finding the opposite. I used to take no pictures at all, and now we take a nice big camera when we go on vacation. I'm amazed at how little I remembered about the details, and the photos bring that flooding back.
Of course, this assumes there were memorable things happening in the first place. If you just saw the sites and that was it, then the pictures aren't actually any better than any else's pictures... And to be fair, other pictures are usually just about as good for most memories.
A picture of the Kaminarimon gate in Tokyo isn't actually that different between pictures, after all. A picture of a certain event (parade?) with it in the background would be different. And pictures of an event like a wedding would be very unique.
You only need a couple though. Like the old days, do some stuff, snap a couple photos along the way, usually only one person in the group even had a camera.
