The pontoon is moored in the reef and we found out once we got there that you could actually spend the night on the Reef, it's something I'd like to do if we visit again.
The was a semi submersible submarine and underwater aquarium as well as seating area and all equipment needed such as rash suits, wet suits, snorkels, fins and floats.
Although I am a competent swimmer I've always struggled with snorkelling, preferring to just swim under water with goggles, however a woman suggested I tried a float so I could focus on the breathing and not the swimming and it was a game changer. I was in the sea head down for almost an hour. I did drift but within the marked area and there was a life guard on the pontoon and a boat on the outer edge to nudge people back into line.
