I always find these tours a bit frustrating because the prerecorded voice-over does not coincide with the speed of the traffic because it varies, so you often have no idea what building is being described because you haven't got there yet. However, I always book this tour for the first day as it shows me all the places of interest and I can decide what to go back to, and it shows me where everything is in relation to where I am staying so I can find my way around afterwards.
This is important in Naples, because the metro staion had mo maps and the names of the stations were different in the ticket search than on the metro plan on the wall, so the central station on the wall had to be searched by Piazza Garibaldi Central station in the ticket machine. Also when we arrived at the information desk in the central station they had no maps either.
If you are staying in a tourist centre you can buy a map from a news stand but if you are out of the centre there are no maps, so the bus tour also supplies a good map.
If you want to get situated with the must see places in Naples, then look no further, the Hop-on Hop-off city tour bus should be your guiding light!
Very entertaining the sites and scenery around Naples specially on this double decker bus audio guides are available in many languages and provides really good information.
Highly recommended to purchase this attraction to get the most out of your visit to Naples if you are visiting for a short period of time.
