We went out on Sun after having booked earlier before we left the US. The boat is very nice and not huge like some of the others. The crew all were both professional and friendly. We are on a long "holiday" for our 25th wedding anniversary. It was our first visit to the GBR. We did the snorkeling and the beginner scuba. Our instructors were fantastic and the scuba was actually easier than snorkeling. On deck, many of the crew came over to ask us how we were and how the trip was. I can not say enough positive things about the staff. The whole experience was great and we would do it again in a heartbeat. My advice, skip all the big excursions and go out with passions of paradise. (Date of experience: Aug, 2010 )
