I know there are a lot of ports on this cruise but overall (if possible to answer without getting too detailed) what are options for getting around and seeing a bit of the areas without excursions? We have only done caribbean cruises in the past and were content with getting off the ship and spending an hour or 2 walking around. (We are not big on group sightseeing.) A few of the ports are Taormina, Sicily, Argostoli Greece, Kotor Montenegro and Split. Are taxis avail close to ports in the bigger ports like Rome and Postiano? I realize this may be complex to answer and I thank you in advance for any advice you may have!
