This was a very nice tour with just the right amount of interesting commentary and length of time. It really filled in a blank spot on our itinerary. It is a great introduction to the Sydney harbour for first timers and those that need a refresher.
The cruise did a complete tour of the harbor and was narrated at points of interest. A great chance for photos, as it came close to the Opera House. Roomy enough to not feel crowded and seating was available. Highly recommend it.
