I have train tickets from Rome airport to Naples Centrale. I need to get to Sorrento. I need to understand the difference between Naples Centrale and Naples Garibaldi Stations. As the trains to Sorrento all seem to all leave from Garibaldi. I googled, and it said they are in the same station, one is the lower station. But then something else said I need to take a train to get from Centrale to Garibaldi, for 1e each. If this is true, do i buy a ticket to get from Centrale to Garibaldi. Then at Garibaldi, buy a ticket to get to Sorrento?
I need help understanding how the logistics of this work. It seems if they are the same station, you just walk downstairs. Or are they not the same station?
