We did the A+B cruise. There was some confusion at the berth as to which boat we were suppose to be on. There is also about 20 minutes wait between each cruise. The cruise down river was longer and more informative. Our cruise upriver seemed very short, it was cut short due to the company using a larger, air-conditioned boat, but it really felt very short. Overall our visitors enjoyed the cruise/s, a nice way to see the Melbourne skyline.
