We arrived about an hour in advance and a line started forming shortly after. It’s nice that in the Dubrovnik terminal there is sheltered seating where you can dine and relax as you wait. We got in line about 30 minutes before the departure time and got good seats by the window. Tip for those wanting to see the coast traveling to Hvar or Split, get a seat on the starboard (right) side though the salt water eventually makes seeing much impossible. Smooth ride the entire way. In the way north, we passed through a gaggle of wind and kite surfers, some of them coming quite close to the ferry.
