Hi Giraffe,
long time no hear

I am quite sure you miss out a lot when not staying in a bushveld camp. The main difference is that there is no shop or restaurant and only up to 15 chalets/bungalows which is making the whole camp far more quietier and less frequented. Sometimes in case of Biyamiti the roads which are leading to the camps are "private" roads which are only open for those who will stay in the camp.
In many bushveld camps there will also be a nice walk to strech the lengs a bit and they do also have at least one hide inside camp and sometimes also two. All bungalows will have the complete kitchen with all utensils as well as a private braai. Most of the chalets are for 4 or more people in the bushveld camps and that is also the different in the price as you will have far more space.
I would recommend that you just try one or two stays in different bushveld camps during your forthcoming trip (Biyamiti is highly recommendable and is also one of the cheaper bushveld camps).
BTW we will also be in Kruger in February so please fly your YR high maybe we will meet each other on the roads
Happy planning
