Despite being a cloudy day the water was warm and we thoroughly enjoyed our day on the Reef. Well organised nad would do again.

Catering was poor quality. The underwater observatory was crammed and hardly saw anything. The only experience I enjoyed was the skoobydoo and it was not included in the package. I had to pay $185 extra for that.
