Venice is one of the world’s top tourist destinations, with 3.2 million visitors staying overnight in the historic centre in 2022 dwarfing the resident population of just 50,000. The aim of the tickets is to persuade day trippers to come during quieter periods, to try to thin out the worst of the crowds. In Spain, the world's second-most visited country after France, tens of thousands of people protested to demand limits on visitor numbers to the archipelago.
