It was the perfect start to the visit as it gave us a feel for the layout of some of the main sites without the stress. Our guide was knowledgeable and spoke good English. The boat trip was the highlight for me. Tokyo is massive, and we got a feel for the scale of it from the boat. The coach was spotless, and everything went like clockwork! Tip: The Viator office is downstairs, under the World Trade Centre. There is more than one tour company operating from there, but Viator's is immediately opposite the staircase.
