What specifically do you want to know? The excursion takes just about all of your port time. It's a fairly long boat ride, followed by a bus ride to get to the place. The time is split in half between two groups. One group goes to the beach while the other group does the animal stuff. They had different areas that smaller groups rotated through - stingrays, dolphins, hermit crabs, parrots. Each group got to spend about 20 minutes or so in each area. They take photos of your time with the dolphins but the photo CD is expensive! They serve lunch cafeteria style. The beach is beautiful! There is shade and chairs for you to use. It was fun for my family. It was good to do once but I wouldn't do it again due to the cost (unless I win the lottery).
Hope this helps!
