When going to places like South Africa, Singapore, etc. you might want
to consider getting multi-entry visas if a visa is required. Although
they usually cost a little extra, it is worth the hassle of having to
queue up, complete the paperwork, provide photos etc.

From South Africa I went to Zimbabwe by bus to Bulawayo and then by train
to Victoria Falls, walked over bridge to Zambia and then took train back
through Botswana and then to South Africa. Also one might want to make
a side trip to Namibia. (I met a South African soldier in South Africa
that delighted to tell me he had been stationed in Nam. I thought he meant
Vietnam and then he smiled and said Namibia.) From Singapore using it
as headquarters, I made side trips to Bali and back, India and back, Malaysia
and Thailand and back.

While you might be able to get new visas getting a multiple entry might
save you some time. From Johannesburg I also took a bus trip to the township
where they then allowed gambling and had a small Las Vegas. The township
and I cant think of its name began with b long name and they had distinctive
stamps for sale. A small diversion if you have the time. Happy Travelling
