My family was gifted an annual pass for the past two years in a row. It really is a great way to spend some time although, note that it can get very hot at the wild animal park and very busy at the zoo, depending on the day or time of year.

If you have the right membership, you can get close in parking at the wild animal park, queue buster access to the savannah experience and at the zoo, queue buster access to the tour bus.

In terms of which is better, I couldn't choose as they both have highlights that make each park special. The axlotls at the zoo for example or the walking exhibit with wallabies at the wild animal park.

If you have time, hit both!
