Find out as much as you can about the people offering the hunting. Is it mainly shooting from the back of a truck, or actually involve stalking.
Is it organised in such a way that the hunting is really "hunting", or so contrived that they drive you directly to the species you want to shoot, and then the animals are so tame, they stand there asking to be shot !
I went in 2017, and found it very disappointing. The whole setup was designed to get you to shoot as much as possible, as quickly as possible. They even used men on horses to drive herds of animals towards us.
We did "stalk" into a group of Blue Wildbeest, got within about 30yds, with them watching us the whole time. It was more like walking up to a herd of cows. And when we did get close, the PH said they had the wrong colour tags on them, so we couldn't shoot anyway

In fact, most of the animals were happy for you to get way closer than was natural.
It destroyed all of my expectations, and the experience for me. I guess I'll go again at some point, but I'll be doing a lot more checking before I do.
The best animal you will shoot, will be the one you have to work the hardest to get.
