European tourist hotspots like Amsterdam and Venice are on a crusade to deal with surging visitor numbers.
Milan is considering a ban on pizza and gelato sales after midnight, as well as enforcing closing times for outdoor areas of restaurants and bars.
The summer of 2023 set a record for Greek tourism, according to The Economist, with 16.9 million visitors during the peak season, even while parts of the country were decimated by wildfires.

In 2019, local authorities limited the number of cruise ship arrivals to two per day, with no more than 4,000 passengers each at a time.
