At TwentyTour we believe that every traveller should have the chance to join an excellent city tour even if they are travelling on a budget. Therefore, at “Free Walking Tour Tokyo” we prefer a system where you don’t have to pay for a ticket in advance without knowing how good the tour is going to be, instead, you take part in the tour first and at the end you can give the tour guide a tip based on what you think the tour was worth and what you can afford. It’ s as simple as that. 🙂
