We went on the last day of "after hours with the animals" for 50% off-- we felt like we had the zoo to ourselves, which was awesome, but it also highlighted a bit of the downtrodden aspects of this zoo. They are undergoing renovations and redesign, so that may have played a big role. But I found some part of the current layout a bit depressing. Nevertheless, the animals were all out and fun to watch, and seemed well taken care of. Both the lion and the jaguar seemed to be having GI issues when we were there, so we got to hear lots of roaring. Good and bad. It was late afternoon so apparently the giraffes weren't interested in eating, hence the feeding option wasn't there.
Overall, a nice visit, but definitely looking forward to whatever improvements they plan on making! For now, I will likely just go to the national zoo and make the trek. Wasn't impressed enough to get a membership.
