This is a great zoo! I don't think it is all that large space-wise but that use that space very well. It took us about two and a half hours to go through it, we didn't do any of the extra attractions, and I think we still missed a couple of exhibits. Yes, they do nickel and dime you for extras but so does every other zoo I've ever been to, but it's really not that bad at all. Just say 'no' when they ask if you want a photo.
