Used the most recent groupon for entrance, well worth it, we spent 6 hours and still did not get thru it all, the expansions are coming together nicely.
Suggestions--
1. Improve the bathrooms- dirty and outdated for the size of the zoo, maybe adding a few more would improve guest experience.
2. Maybe have a ride wristband or ticket system, when you have a large family and charge $6.00/ride, it adds up quickly.
We also visited Dillions, the food was not great, but was moderately priced, and the service was slow.
Other than eating elsewhere and having more time, we will be back in a few months!
