Booking mid-market hotels is easy, just go to booking.com, filter to 8+ score, four stars, go to the map and pick the location, done.

Finding good-but-cheap hotels is harder, because it's zero sum. You are looking for hotels that are mispriced usually due to a lack of information. AI doesn't solve this problem, it actually makes it worse by fixing inefficiencies in the market.

I really find flight booking is fine, for the amount of money at stake.

By contrast I find ordering food to a table with a QR code enormously complicated and tedious for something that should be simple.
