Hi Carol,

What time will you arrive at JNB?

The Sandton Tower and the Michel Angelou are centrally located around Sandton City and Sandton Square. That will at least offer some choice of shopping or restaurants if jetlag keeps you awake.

I would compare the Holiday Inn to the Le Guardia ( New York) Airport hotel. There is nothing to do in the immediate vicinity unless you take a cab drive.

Happy research!
Bye
Anne
