This is the biggest and best zoo I've been to. We were there for a full 8 hrs and barely walked through all parts of it. I love riding the tram, seeing the animals closer than most other places and seeing the hippo swimming. Too bad the polar bear went hiding and the pandas are not there.
The only part I don't like is the paths are confusing, there's many split points and it's hard to visit all animals without repeating some paths.
