Officials announced the new rules, which are set to take effect in January, on Friday, according to a report. Tourists not staying overnight in hotels or looking for other lodging will have to register online for the day of their visit and pay a fee ranging from $3 to $10.50 a day, city officials said. Those who ignore the new rules will risk fines of more than $300. More than 80 percent of visitors to Venice arrive just for the day — more than 30,000 to 40,000 people a day, Bloomberg reported. In 2019, there were more than 19 million “day-trippers” in the city. Last year, Italy’s government approved measures to ban large cruise ships in the Venice lagoon.
