If you have kids and plan on making a special trip out here to see the mermaids, maybe reconsider: website lists "mermaid swim" hours, but we arrived to see two girls sitting in chairs beside a Meet & Greet sign. One was wearing a tail, another was in heels, both wore bored expressions and neither got in the water at any point. How disappointing.
More exciting than the cloudy, circular tank of dull, muted fish was the adjacent waterfall area of koi, ducks, and turtles at the Bass Pro shop.
