Highly recommend the tour bus! It helps you tour around the whole park and almost cover most spots. We got several pictures that so close to the polar bear.

A recommend route: entrance - tour bus - walk from bus unloading zone to skyride - skyride - visit around (Polar bear, 4d movie, etc) - walk to kangaroo bus stop 2 - take bus and leave at kangaroo bus stop 1 - visit around (Koala, giraffe, zebra, etc) - go to exit
This route covers most spots and saves time.

Overall, we had a great experience here though the weather is pretty hot.
