We will be in SA in July with or 2 kids aged 10 and 12 (third time to SA). We will be visiting , a.o., Kruger Park and 2 nights in the Sabi Sand. I've some budget left for either 2 nights in Madikwe or 2 nights in Timbavati. We could do MAdikwe at the beginning of our trip.
However, budgetwise we could only do Mosethla, which actually appeals to me (even with kids - we have been in a similar place before).
Most important are the quality of the game drives. Not necessarily the big 5, but would also be interested in oher animals.
