Overtourism has been a longstanding problem for Venice now. And with the country soon opening up its doors to travellers right in time for summer travel, it is once again looking at a massive influx of travellers in the upcoming months. In order to deal with this recurring problem, the city might soon introduce a pre-booking system for all visitors looking to enter the city. According to reports, the city may soon introduce an entry fee for day trippers — up to €10.
