I thought I was very organized for my KNP trip until I got there. I think my overexcitement of being there did not allow me to focus on all the aspects of the park. I tried to do everything (family traditions) as I have always done in the past. My pick of camps was not the best as all the game seemed to be down south and so I found myself racing against the clock just to get to a good sighting area. Our top animal sightings were not good at all except for the wild dog. It may seem like I am complaining but I am not. I know better for next time.
In my (not humble) opinion you do, you're complaining and show some disappointment. That's really so sad. You did a looong trip, so did few others. To really well organize such a trip, it is something special, it needs a lot of things to be considered.
But, unfortunately you cannot plan sightings, it's simple like that. Just imagine to sit under a tree in the shadow, for a long time and as long sun movement allows you (what I did). You see nothing and leave, deeply disappointed. Next moment, next driver stops at same place and there they are: Hords of lions, a fine bloody kill, cheetah, leopard mom plus cub in the tree ... You'll never know that. As you left in disbelief and disappointment.
Sightings cannot be planned. Enjoy what you "see", there's so much!! and if it's only the sound of your environment, the smell, it's that great, impossible to describe. Nobody can grant sightings. If you need granted sightings, well: there always is a zoo somewhere.
You're from Canada, a place I "know" a bit. Usually, coming back every year, I use to visit the "hidden" national parks w/o millions of tourists: I did not see any Grizzly or Black Bear more or less than in crowded places like Banff, f.e.
Just after leaving back home, my email account usually is full of messages of friends telling me what they just saw (after I left) in (as an example) Algonquin Park: Hundreds of Black Bear, I did not see a single one. I walked for hours, canoed for days: No sighting. But the environment itself is so thrilling, wonderful, calling me to come back - didn't you have anything like that during your trip?
