South Africa travel advice?

Hi all

Can we get some recommendations for the following.

1 - We have a single person arriving in CT at night and wanted to organize a reliable, private driver to pick them up from the airport and bring them to our hotel on the waterfront.

2 - We would like to hire a private driver for the day (6 people) to take us to some places, like Chapmans Peak drive, Cape of Good Hope, Lions Head, Boulders Beach/penguins, Clifton, Camps Bay, Any suggestions on other places to see for people who have never been to Cape Town would be appreciated. What sort of cost are we looking sat for 8-10 hr day?

3 - We have a 2 days in Joburg when we leave and wanted to do a tour of some kind and include the museum, Soweto, Mandela House etc - Are these tours quite safe to do?

Thanks in advance everyone
