Once again, I seek the wisdom of this great group of travellers.

Going to the Med in two weeks and I am wondering about how well we (my 18 yo niece and I) can experience a couple of ports without doing formal tour or shore excursion. She is not interested in8 or 10 hour long tours (me, either) so I'm trying to scope some things out in advance.

So, in Sorrento, Naxos and Santorini, can we just get to the center of things and wander to get a feeling for the place? Or do you recommend certain sites in those ports as 'not to be missed'? I've been to Sorrento before and done the boat to Positano, ride down the Amalfi Coast thing - very beautiful so we might do at least a part of that. We want to see what life is like on Santorini - we had originally planned to spend a week there and then changed our collective mind to take this cruise instead.

All opinions are welcome and greatly appreciated.
