I had a 7:30 am ferry to catch in the morning, for a 7 hour boat ride to Dubrovnik. I would rather take the boat, which was a little longer rather than bus. The boat ride was great. We passed many small islands and I was able to walk around.
I met a Brazilian guy on the boat named Diego. He and I decided to team up and got a cheap place to stay in Dubrovnik. We walked down to the old city, it's a cool looking old city surrounded by a huge wall. We found a great bar just outside the city wall on the sea to watch the sunset.
