I am with a group of 4 who are renting a car from Nice Airport and exploring Nice and the surrounding areas for 3 days/nights before heading to La Spezia to explore Cinque Terre for one day and flying out of Milan.
My question is regarding the most economical way for 4 to get from Nice to the train station in La Spezia as opposed to keeping the car that we rented in Nice and dropping it off there. The drop off fees from France to Italy are over 200 euro plus daily fee/gas/insurance/etc. We can always rent a car in La Spezia and drop it off at Milan airport so our main concern was how to get to Nice to La Spezia without using a rental car and in a fashion that doesn't make us lose alot of day time and cost too much.
Thank you in advance.
