In all my world travels -always get tew days, best way to get a quick overview of the city. Do one route one day and other route the next.
We were able to view the sights easily whilst sheltering from the rain. We did the full circuit , then part of it before alighting to visit Greyfriars. The driver was very helpful and even dropped us further up the hill so that I did not have to walk so far. I will definitely use the tour again.
