Dubrovnik: cruise-ship hours, and the walls at 8 a.m.

Dubrovnik's old town is small, and when two cruise ships are in port the main street is a slow shuffle. Check the port schedule online, walk the city walls at opening time (the ticket is pricey but the view is the point), and spend the midday hours at a beach or on Lokrum island, 15 minutes by boat. Evenings after 7 p.m. belong to the people staying in town. The cable car to Srđ hill has the best panorama at sunset.
