This was such a lovely thing to do. First, get on the cruise at Kings station wharf. You will get on with maybe 10 other people, be seated first and get to eat before 40+ people board at Circular Quay. The lunch was buffet style and I thought it was very good. After lunch we went up top and took in the views. They were incredible and they narrate what you are seeing the entire time. We finished our lunch before most of the people did and went up top and almost had it to ourselves for awhile. I would highly recommend doing a crusie with Captain Cook on the Sydney harbour. It was a highlight of our trip.
