I went whale watching with Captain Cook back in 2016 and had a great time. We rebooked for today which left us very disappointed as we are at the end of our Australia trip and really wanted to see whales close up before we go home.
Firstly, the cruise was booked for 1:15, we did not leave the port until after 1:30. Whereas other companies nearby which were also booked for 1:15 left boarded prior to this time and left the port at 1:15. Following a fellow passenger suffering with sea sickness just as we got out to sea, we returned to Watson's Quay to allow them off the boat with several other passengers. I could not hear what was being said over the speaker at any point outside as it was not loud enough, so had to ask staff when we stopped at Watsons Quay what on earth was going on. We were first told that we would be returning to Circular Quay and could enquire with the booking office to explore our options. However I was then advised that we were going back out whale watching following the drop off at Watsons Quay. They did not mention at this point that this would be for about 15 minutes (having lost about an hour of the trip returning the unwell customer back to the quay and then getting back out to sea) and we would still be returning to Circular Quay at the same time as previously planned, I wrongly assumed that we would be allowed a little more time. We did thankfully see a couple of whales, but just their fins surfacing from the water, however we did not have time to hang around in the area and wait for any more to resurface due to the rush to get back to Circular Quay.
I would recommend that others book with other companies who offer 3 hour trips as it gives you a bit more time to see the whales, and should anything go wrong, it will hopefully mean you're not rushing back. These companies also seemed to set off from Circular Quay before us, despite having the same booking time.
The problems above were clearly not the staff on boards fault, but I just feel as though the situation could have been handled better and communicated better with the remaining customers on board.
