Concerned city officials may pass laws to ban groups of over 15 visitors wandering there, and eventually forbid tours entirely. They want to prevent overcrowding, but as one city father complained “also because it is not respectful to sex workers. It is outdated to treat sex workers as a tourist attraction.”

The Dutch capital has already banned current so-called free tours, where guides and other locals encourage tourists to join them at the Red Light District for a fee plus a city tax. So, on your next visit to Amsterdam, understand and obey the rules while wandering the sights, streets, hookers and canals.
