We also went on Ko Olina Ocean Adventures in November and loved it. The staff was wonderful. We brought our two kids (6 and 8) and they were awesome with the kids. They helped them feel comfortable in the ocean and brought urchins, sea cucumbers and other creatures from the ocean floor up to them to check out. The food was ok, but we were there for the snorkeling. I would definitely recommend it. We even walked back, it was too bad.
