Our tour of Dubrovnik consisted of a trip up to a view, then down to the city again for a tour. At the end of the tour we were free to stay as long as we liked, then return on a shuttle bus to the ship.
Dubrovnik is a beautiful city. We walked about and I took pictures, and lost my group. This was not a problem, as I knew where to go.
This area has one of Europe's oldest pharmacies, or the oldest.
An area I liked was a street we walked along which was restaurant seats as far as the eye could see. Which wasn't all that far!
There is a wall around the city which you may walk around at a small cost, but I did not have a lot of time, so that can be something for next time.
