I am arranging for a taxi to pick us up from our ferry and take us to our next destination. Are the prices quoted firm, or am I expected to bargain? I don't want to be foolish and take the first price quoted, but I also don't want to insult anyone by offering a low price. What would be a fair price to go from Ermioni to Nafplion?
I recommend you may want to email your hotel and ask them - they may even let you arrange a driver for a set rate. Many of the hotels in Athens do that now from Airport/Cruise Harbor for about the same price (or 5-Euro extra) to have the professional driver waiting with your name on a sign. Takes the guess work and adventure out of the default taxi driver you come across.
