We booked the morning slot to the green island because we were on a cruise that left late afternoon and this was one of the trips to the barrier reef that came back at lunch time 1pm. When we arrived at the cruise terminal we were told they were extending our time to 2pm at no extra cost which was a nice surprise. The island was fantastic and the extra for the suit I hired to protect me again jelly fish was well worth it as it added protection from the sun which we hadn't factored in. Overall excellent trip, definitely a booklist trip for us.
Not enough time for anything really. The boat ride out was good the semi submersible sub was too short and the fish came because they were fed. Then we had 40 minutes to snorkel off the beach which was ridiculous and to top it off there were hardly any fish in the beach area. this trip requires more time and a better place to snorkel
