Booking is the website with the highest density of dark patterns per pixel I've ever seen.
Red texts hurrying you to make a reservation in virtually every <div> on the page ("only 2 rooms left", "someone just made a booking", "12 people looking", "Booked N times today", "You're lucky to see this room, normally it's booked!", "You're lucky to see it for $50, normally it's more expensive" etc.).
All of those texts are flashing/animating so there's a lot of moving things on the page.
When you're idle for a while and switch the tab in the browser, after coming back you get a popup urging you to make a reservation. Basically you're sweaty after the process.
I reserved my hotel lately with Booking and I will actively try to avoid in the future if possible.
