Taking a private car is very convenient. Depart at 8:00 AM and arrive at 9:00 AM. The driver will clean the car and drop you off at the safari first to see the animals. Then, go to the marine park area and tell the driver what time to pick you up. This way, you can see all the "Sus" (zoos/parks). The marine park is essentially a zoo, and you can skip the orangutan zoo. There are some animals you need to pay extra to see, like the giraffes. You can only see the elephants during the show; after the show, I couldn't find any elephants. So, it's best to go early.
