We paid for a shuttle from Regent in Oct, 2006. I think it was 10-20 dollars per person but I can't remember. Hated it as we only had approx. 3 hours in the town. They left late and came back early. The next time I was there I noticed that cabs were plentiful. The cabs drop you at the entrance of the main street and it is a 5-10 min walk to the Roman Theater. Lots of ceramics and gourmet food shops around. Bam Bar makes the best granita. It is a lovely port.
