Welcome to the forum Arnold.
Firstly if you only have a few days like 2 or 3 I would advise staying in one camp so you can maximise your time in the area.
Skukuza is the biggest and main camp in Kruger and really has everything you need, nice accommodation, restaurants choices, good shop and take away plus a good network of roads and you can cover down south to Lower Sabie and even Croc Bridge in a day and even north as far as Satara and back on another day during that time.
Being the biggest and busiest camp your chances of getting on a Bush braai would be better there than the smaller quieter camps.
Prices vary from around R850 to R950 per person depending on the restaurant that is doing the catering.
You have to contact the camp directly requesting the braai but maybe if you are fixed on a specific day you could just make enquiries from reception once there.
But otherwise there are also the guided morning, sunset and night drives to consider or even one of the guided walks.
Please do ask if there are any further questions we can help with.
