We got a "walking tour for 4" groupon for $17 this weekend. It was a great deal and so worth it. We all really enjoyed it. The staff was very friendly. Our tour guide was named Molly I believe and she was great! All of the animals came out to play and we got to feed and pet them. I'd most definitely go back again. There's was a lot of poo on the ground of course so just wear the right shoes.
