You cannot rate this experience. Anything you see in Kruger, is based on pure luck and good timing. I have been to Kruger twice in the rainy season, and you cannot decide, what you want to see. The animals do not have tracking devices, as some do in the private reserves. You cannot go to Kruger and order a lion or a pack of wild hunting dogs.
I went to Kruger for the first time, it was in the early morning, meaning we had all day to look for animals. The first thing that happened was we entered Kruger in the bus, and out of nowhere came a big pack of wild dogs, surrounding the car, relaxing on the road, sniffing each other. It was truly magical. They started running slowly, as we drove beside them, while getting eye contact with several individuals. We saw lots of zebras and giraffe, and quite a few bull elephants too. Baboons, hyenas, vultures, buffalo, duiker, eagles, exotic birds and hippos in the dam.
Kruger is an example of true wilderness. Depending on where you go (Kruger is a transfrontier park, crossing several borders), you will see different nature including different wildlife. If you join a good guide, who has contact to others on drive, they will sometimes call each other, if they found something everyone wants to see, e.g. lions or cheetahs. If you go to Africa, and you're dying to see a cheetah, you should go to a private reserve.
Would go to Kruger anytime, but next time I will bring better binoculars, more time and my own car maybe! :-)
