We did the tour back at the end of April and were not thrilled with it for several different reasons. It was a lot of walking in the heat and the encounter with the penguin(s) was really smelly. The lady who came out and held the penguin seemed like she would rather have been somewhere else and was none too friendly, or maybe she just wasn't a people person! We also got to see a polar bear who looked so unhappy in a little room and a couple of seals in a tiny little concrete containment room. On the other hand, we really enjoyed the Predators tour because it was packed with good information and a little excitement and the sharks didn't look irritated or too confined. We had a good tour guide, too!
