In a few weeks 4 of us are on a cruise that docks for a day at Pireas, we want to see the Corinth canal and get to the Acropolis, my plan is to arrange a hire car to be delivered to the port when the boat docks, use it for the day before having it collected from the ship in the late afternoon. Has any one here driven in Athens and parked near the Acropolis and can suggest a car park ? A bit of a long shot, I know.
