Hi Jo and Sam,
It sounds like this is your first visit to Kruger, yes? You will absolutely love it!
Everyone has a different idea what the perfect trip is, so you can only take everyone's opinions and decide which type of trip you want to do.
Personally speaking camping is the only way to go ......it works out to be so cheap.
I have been on many truck trips all around Africa (Kenya, Tanzania, Uganda, Zaire, Namibia, Botswana, Zimbabwe, Mali, Burkina Faso, Mauritania, Senegal, Western Sahara, Morocco) and they were all wonderful ...BUT on an organised trip of any sort, whether it is a camping truck trip or a safari game lodge trip, you are always at the mercy of how long other people want to sit and watch. Once I discovered how cheap camping and game park fees are in Kruger and how amazing it is to do a self drive, Kruger seems to be almost the only place I visit these days
With 2 of you the value is even better. I buy an annual Wild Card and make sure to visit twice in the 12 month validity to get the most value.
The international daily conservation fees are only R204 per day each (cheap compared to other countries game park fees) so, if you are planning on staying for 4 nights you would be in the park for 5 days making a total of R2040 for two people (£148). A Couples Wild Card is R2330 so the sake of an extra £21 you might want to think about going back before April 2014? (I take it you are from the UK using sterling?)
Camping in the main camps (Berg-en-Dal, Satara, Lower Sabie etc) costs just R190 a night for two people if you book online (£14) and you have access to the communal kitchen so you can bring all your own food.
Your budget is a massive budget if you camp and bring your own food.
I always rent the smallest, cheapest car through online brokers like http://www.argusrentals.com/
paying around €100 (Euro not Sterling) for a week and, despite being lower to the ground and on my own, I have always managed to have incredible sightings. I just checked for 5 days in April and they are quoting £65.93.
The drive to Kruger from Jo'burg airport is 393 kms and always takes me 4 hours - 4h 15m without breaking the speed limit. The people who quote 5 hours from Jo'burg are probably stuck in traffic getting OUT of Jo'burg but I simply drive straight from the airport onto the N12 and N4....or maybe I have just always been lucky!
My last petrol bill in September for the return trip from O R Tambo and over 1000 kms driving around Kruger for 8 days came to R1400 (£101). Tolls there and back are currently R310 (£23).
I do usually go on a couple of the Kruger Park night drives as well but that is an optional luxury.
Feel free to pm or email me if you think I will be of any further help to you. I will be back there in a couple of weeks .......this time for 16 days, my longest time there yet....I can't wait. Every time I go I meet the lucky people who are staying for a month at a time .......who knows, maybe one day I will be able to do that too!
I hope you have the most incredible 5 days in Kruger and, of course, a great time at the wedding
