Do to the extra rain this spring the zoo is green, clean and  lovely. We loved the discount, although there was 4 of us and our grandchild, and the voucher only went to 3.  I don't have room on my older phone for the Groupon app, so brining up the ticket was about a 35 minute hassle, and the clerk was not as all helpful. At ALL, and only two other guests were entered that time.  There was a big assortment of Animals, and appeared to be well cared for.  I would recommend a trip there.
