Honestly I wouldn't recommend booking at all it's overpriced and horrible

I would get a ticket via a tourist office which includes a guide. He will make your trip there far quicker and more efficient. Yes, you can take photos throughout the trip. Whilst animals cannot be guaranteed, you are sure to see plenty. You can take food to entice them, too.

It's a nice marketing mumbo-jumbo phrase, that's for sure. And here we wonder how cynicism came to be. To be fair it is more than a zoo, and seeing animals in surroundings closer to their natural habitats is something. Also there are some activities aiming at educating and conservating. But yes, it is a zoo, and a touristy one, too. But animals are much healthier than most Thai zoos.

It's about 3.5 to 4 hours, depends just like the other replies. And the kids will love it.

I paid 700thb at a vendor near the night market for entrance to everything and transport.

Not an environmental driven park at all. Also, your experience may vary at this place; we did not like it, as many aspects of it is poorly managed.
