I wish people would realize that their vacation photos should include, well, them. When I travel, I'm taking pictures of my family doing things, not the things they're doing. No one needs another generic copy of just the Eiffel Tower or the Statue of Liberty.
I recall a story I once read about an elderly woman showing her family videos from her trip to the Grand Canyon decades before. You could hear her shooing her family out of the video so she could get a good view of the Grand Canyon, and afterwards she just wished she had more video of her family, not of a landmark. There are innumerable photos of most of these places, only a few of family and friends.
Of what? You assume I just go to famous landmarks and take typical photos of them? A small fraction of my photos chorus be obtained online. Most are fairly unique.
