I'm planning our train journey from Nice, France to Monterosso (in one week!). The train from France arrives to Piazza Principe in Genoa, but the train to Monterosso leaves from Genova Nervi in Genoa. I can't seem to find- how to get from the one train station to the other? And, do I need to reserve these tickets now, or can we easily walk up and buy tickets same day? Then we could just figure it out there, much easier as we're leaving on our trip tomorrow morning. Advice, please!
