Fascinating!
I've been to quite a lot of the places listed, but decades ago.
I first saw the pyramids, aged 15, in 1977 and was blown away; same school cruise, The Acropolis, Santorini and Venice. Plus other wonders not (yet) dissed on here!
NY, aged 26, never seen such sky scrapers, despite London, by then! Wasn't underwhelmed by the Statue if Liberty, at all! Liked the White House, awed by Niagara (tho recognised the touristic tat all around!).
The Grand Canyon (recall its 1988 for me) blew me away; SF was as hippy and alternative as I hoped.
Saw Rome in 1995, enjoyed it; St Peter's- just wow!
Okay with Bruges, prefer Ghent.
Sydney beaches? Yeah, had some great backpacker moments on them, can't be underwhelmed- and19 years ago, my DSs loved them!
Paris, been 3 times, each better than the last. Last visit 3 years ago, expecting the Louvre to be packed with Chinese, which it was. But still a very successful visit! Speaking of which, Great Wall of China, circa 1986, at Badaling and at the coast. Amazing.
However- I get that so much of what I saw and loved was before tourist hoards/cruise ships.
