I went as part of a Wild Arena workshop back in 2008.
You'll find much better opportunities for taking decent big cat photos than at a zoo (and this is not a zoo!), and it's less crowded. You'll also get a chance to get closer to them - there is just a strong wire fence separating you and the cats.
Shooting through the fence can sometimes be awkward, and you have to be aware of the background as it can be distracting in photos, but this is only a small downside.
However, the only way around this is to go to the animal's natural habitat or a safari park, but then, you are not guaranteed to get this close, let alone even see them. By going to the WHF. you will get the chance to photograph many different types of cat such as Snow Leopards, Lions, Tigers, Cheetahs and the lesser known varieties, like Servals.
The other advantage is that if you are lucky, you may be able to touch some of the animals! As it was so hot on the day I went, the cats were just flaked out, a tiger and a lion were lying against the fence in their enclosures, so I was lucky enough to get to scratch them (and I can tell you that lions can indeed be ticklish) - I have to point out that at least one member of staff was keeping an eye on things for our safety.
If you ever get the chance, I'd say go. If nothing else, you get the opportunity for some great photos, and really appreciate exactly how BIG some of these big cats really are...
