Could one of the resident experts confirm that from Davidka Square I should take the tram to Mount Herzl tram station and then walk to Yad Vashem? A quick Google maps search seems to suggest this would involve a 35 minute walk when I get off the tram at mount Herzl. Is this correct? If so, are there taxis available in the area i.e. is there a taxi rank nearby? My itinerary is quite full, and the 35 minute walk there and back would impact on the time I would have in Yad Vashem itself.
