Italy’s famous floating city has a problem - too many tourists are visiting Venice during the high season. The city authorities recently announced a plan to charge day-visitors a €10 tax during the busiest periods. But many are sceptical about the plan, saying it doesn’t go far enough to address over-tourism. The BBC’s Vivienne Nunis joins the crowds in St Mark’s Square to assess what can be done when a holiday destination becomes a victim of its own success. And she explores how other popular destinations such as Hawaii and the Isle of Skye in Scotland are addressing the problem. Producer: Vera Mantengoli (Image: A gondola in Venice. Credit: BBC)
