“The effect won’t be very big,” said Ko Koens, a professor of new urban tourism at Inholland University in Rotterdam, the Netherlands. He also said that in the long run, the capping of hotels could make them more expensive to stay at.

While this ban alone would not make a huge dent in the number of visitors to the city, Mr. Koens said, taken together with other initiatives it could make Amsterdam a less-appealing place to visit. But, he said, “For now, visitors don’t seem to mind.”

In total, Amsterdam has nearly 42,000 hotel rooms that can accommodate more than 92,000 people, according to Statistics Netherlands, a governmental institution that compiles data about the country. (In total, the Netherlands has more than 150,000 hotel rooms.)

Amsterdam’s initiatives to rein in tourism have been largely focused on its crowded city center. But as long as Amsterdam’s airport, Schiphol, continues to be a major European hub, it won’t be easy to keep visitors away from the city.

“There are no simple solutions,” Mr. Koens said. “It’s super complex.”

Amsterdam also announced this week it would start cutting the number of river cruises allowed to dock in its waters. In 2023, that number was 2,125. In 2028, the city wants it to be halved, with no more than 1,150. The city predicts that effort could reduce the number of visitors that come into town by 271,000. This proposal, the city said, is to improve the quality of life for residents and to reduce emissions and crowds.
