My partner and I booked a night cruise to see the Vivid lights and we had a very good time.
The vessel is very modern and roomy, with plenty of space indoors and outdoors and an open rooftop. Sailing was smooth and touched all relevant Vivid landmarks, particular note that the boat goes all the way into Circular Quai so you can see lights from relatively close distance.
There is also a bar on board which serves alchool, soft drinks and snack.
Staff was lovely and the whole service was seamless.
I would highly recommend this cruise particularly if you would like to grasp all major sydney Vivid lights in one go (cruise last about 1 hour) or if you have limited time in Sydney.More
