We didnt do a tour we got off and walked up to the town and looked at the oyster market which was good. vigo is very hilly and lots of steps not brilliant for disabled but worth a visit. oh by the way the man playing a violin as you come out of the customs building is hungarian so we were told and not spanish lol
We did the tram tour which was very good its half a day and very interesting go around the old town of lisbon and its so sad to see it so run down and graffitti on every building, you get given a glass of port and portugese pastry and then back on the coach and taken around the wealthy side of lisbon sight seeing back to the ship which leaves you half a day to do what you wish.
did the dolphin watch and that was great saw over 200 dolphins and the guide was british and very good and new where to sail to to see them and how to attract them excellent couple of hours but sadly only half day in gib.
