we will be in Corfu for 10 hours with our cruise ship in October. I am trying to decide between a cruise ship excursion and just winging it. Is the Achilleion Palace worth seeing? and i would also like to see Paleokastrista. If we hire a taxi to take us around, can we negotiate with them or are the prices fixed? And if they are fixed, is it by the mile or the amount of time that we would have them?
