"Not quite a city, but an Airport.
Kansas City Airport.
I mentally prepared myself and everything.
It was like being inside a cardboard box. They had security checkpoints at the gates so once you went through security you were in a pen like livestock. Oh and in that pen? One stall and one urinal. For like 100+ people."
Mona Lisa, Stonehenge, Vegas, Paris,etc. Since everyone knows these places, obviously hordes of tourists go there.
Which means vendors and scammers flock there to make money of them. Which means extra security. Which means facilities need to be made to handle the people but make it uglier.
And obviously Paris, Dublin, Vienna, etc are not the just the beautiful cities from the movies we have in mind (that often take place 100 + years ago.)
They are big modern cities too with lots of traffic.
If you travel, do the research and find the many treasures few tourists visit.
Avoid the city centres and go to the outlining neighbourhoods where you might find a glimpse of the "real" culture of an area.
