The aquarium isn't very large; a visit can be completed in about 2-3 hours. You get very close to the penguins and sea lions, and the dolphin show is quite entertaining. There's also a raffle before the show (for a fee). It's a great place to take children for some fresh air.
KK Day's service was excellent, and the local tour leader was very responsible. It was raining heavily, but thankfully the sun came out in the afternoon, and we could see the beautiful nemophila flowers – it was truly spectacular! A very pleasant trip.
Excellent guide. Excellent trip. I was a little bit worried about finding the meeting place. It turned out ok.
