My sister and I are traveling to Florence end of May/beginning of June. We have already booked a "tour of Tuscany" through Walkabout Tours and saw where they offered day trip tours to Cinque Terre. Which do you think allows you to spend more time in each of the towns? We are ok with taking a very early train and getting back to Florence late. Is the train ride a time-sucker vs going by private car or tour bus? Thanks!
