South Africa is not a difficult destination for seniors to navigate, with driving on the "wrong" side of the road probably the most intimidating aspect you'll have to face. Admission prices to attractions are often reduced for seniors (known as "pensioners" in South Africa), so don't be shy about asking for discounts, and always carry some kind of identification, such as a driver's license, that shows your date of birth. Accommodations discounts are unusual; national parks, for instance, may offer special rates, but these are for South African nationals only.
