Hi Deb Nurse,
There are currently 8 people booked on this trip.
The tour manager will be more than willing to help you arrange the other excursions, however, they will not actually do it for you. They will make suggestions and try to help where they can. Please note that there is a full day excursion which includes a Great Barrier Reef cruise, already included in your holiday.
Kindest regards,
Monty
