I have visited the Kruger park over 15 times with my family over recent years. Tom Kelly's overview of the Kruger gives the impression that it's hard to eat cheaply there - but the Kruger is a great pace for a budget family holiday. You can stay in cheap accommodation at most rest camps (usually fixed safari tents for two or four or budget huts for two-six which are spotlessly clean and have comfortable beds and a wash basin). In addition to more expensive restaurants, all the rest camps have cheap cafes and shops selling food so you can eat well indoors or have a BBQ (braai) under the stars for next to nothing. In general, most of the wildlife tends to congregate in the Southern area of the park (from Skukuza down to Crocodile Bridge and across to Malelane)so this is the area I would most recommend - but the Northern areas of the park have fewer tourists and thus are more peaceful.
