We arrive via cruise ship to Piraeus port and need a taxi with our luggage to a hotel in Athens. Are we better off pre-arranging a taxi or just catching one at the taxi stand? At the taxi stand, what should I expect the cost to be to the Plaka area? I've already gotten a couple of quotes for a pre-arranged ride and am curious if it's necessary as I'm not sure what time we will be disembarking. Thank you so much for your help!
