Oh yeah I think everyone that works there is family....if you volunteer it would be more like in landscaping or helping direct traffic/parking, so you wouldn't get to interact with the animals. I'd love to, though!
I signed up for a yoga class called "Yoga with Tigers" a few months ago which was out in one of the walkways, so we were surrounded by the animals.....it was so cool....actually the ticket I bought for that included a free one-day pass, so that's what I used today. I'd love to sign up for another one!
