Spiros quoted me 45 euros. My recollection from B2B was that the Intercontinental was around 45 mins to an hour, so should be approximately the same. Don't know how Saturday night traffic might be, but if you book the transfer with him he might be able to give you an idea. I just emailed him with our arrival info and he confirmed back in around 24 hours. We are also using him for transfer to the ship, which is 35 euros.

He says the restaurant, which is at the top basically of the plakka, is walkable for those in "good shape" lol about 15 minutes and he will give me directions for doing that. But you could take a cab from the hotel and if you are lucky you might get a driver who knows how to get to the top, and its just a couple of doors, or if they drop you at the bottom of the stairs, you just have to walk up tons of them and its right at the top.
