I have posted about what you have asked. I have chosen the charter company for the boat and for the location, not by the itineraries.
I did not follow any of their itineraries. I have bought pilot books I have studied them at home and I made my own itinerary and it was not a fixed one (depending on the wind). There are so many beautiful places, nice historic towns and charming little island towns that you cannot enjoy 1/4 of them in 15 days. I have sailed a lot more than what is purposed on the itineraries.
