Top-3 authenticity (2026)
Kyoto · Lisbon · Fez. Kyoto's score reflects the Gion Corporation's enforcement against selfie-tourism — measurable in review sentiment shift after Oct 2024.
Bottom-3
Venice · Dubrovnik · Santorini. All three now score below 0.3, meaning tourist-trap n-grams outweigh authenticity mentions 3:1.
Surprises
Marrakech scored higher than expected (0.68). Despite widespread QR scams (see /scams), review sentiment around the souks remains strongly authentic.
