Actually I am not fully satisfied with the service.
Review by confirmed purchaser
We waited so long for the bus to come to the station. Also not all the buses go to the Madame Tussauds so we had to change the bus and again we waited for the other bus to come. While waiting we lost so much time. I think people can walk wherever they want to visit in London. Many attractions are close to each other and it is easier to walk than to use the BigBus tour. The organization will give more acknowledgement to us about what to do, how to use the BigBus in a more efficient and useful way.
