Hello Cindy We operate vintage Route Master Buses, and although we keep our vehicles in the best possible maintenance condition, there will be times that unforeseen maintenance issues may arise and result in a disruption to the tours, or cancellation . Every single customer was contacted directly with a full explanation and many passengers where very understanding this issue was outwith our control as we cant predict a mechanical failure many passengers rebooked and those who couldn't where fully refunded immediately within an hour of the cancellation
