My children and I love the Louisville Zoo. We are members so we frequent it whenever we get the urge. The 4D ride is great. The trains and back up and running again, but we have yet to ride those since the closure. I love the seal and sea lion exhibit. I think it's my favorite part. The only downside to the zoo is that you aren't guaranteed certain animals will be on display or at what times. There have been many times we have not seen the polar bears or the grizzleys, etc, but since we are members, we just move on and hope we catch them next time. I can see how this would be frustrating if you do not frequent the zoo and came just to see them.
