The Waikiki Aquarium is nice, but it's very small, and we cruised through it in an hour. It's no Monterey Bay Aquarium, that is for sure!!! There is still a lot of neat things to see, and a lot of the fish and critters you see are indigenous to Hawaii's waters. Some of the tanks weren't labeled as to who their inhabitants were, so that was also disappointing. Also, some were freshwater fish that you can buy at any tropical fish store (not Hawaiian natives.) A nice aquarium, but I would recommend saving your bucks for something a bit more spectacular, as it wasn't cheap.
