We booked this independently as it was something we really wanted to do and we had a great time. There is no guarantee that the dolphins will oblige as they are wild animals. However, our skipper Kate found plenty of dolphins for us but they didn't want to play once we got into the water and as such Black Cat gave us a partial refund. My wife and I had a good laugh trying to get our wetsuits on and off which just added to the fun. A great day and to be recommended.
