I honestly wish we could spend a couple of days at the game reserve where he works, but at about £450 a day out of our reach. Also a 7 hour drive from the nearest international airport. However I guess we may get a discount as he is one of the more senior people in the organisation. LOL!
So lovely you had a wonderful day with your son, and proud of what he is doing.
We have been to SAR twice on extended holidays, and you certainly would not have to drive for 7 hours, direct flight to Johannesburg or Cape Town, then an internal flight to wherever you son is situated, would cut down on driving. But even then, you could break up the drive and stay, very cheaply, at a very good standard of B&B somewhere.
You certainly would not have to pay £450 a day to stay either. You have not said where he is, but staying just outside of the park will be a quarter of that price, and a very good standard of accommodation. I am sure they would allow day visits if he works there. Is it one of the SANParks?
The accommodation we have experienced in SAR on both our visits have been rather excellent, and at nearly 24R to the pound, you are literally quids in. The SAR is really cheap for UK visitors.
Get over there, you will love it, great for getting up close! 👍
