Hi there, sorry I havent replied before cant blame it on being too busy though...
I am not exactly sure what the lenghts of trips are for South Africa in the winter as it depends on flights, fleet etc, I think Jo'Burg is still 2 nights/3 days. I guss the best thing is to speak to the person who is organising your trip regarding the Cape Town.
All trips are based on social life...HKG is another good one saddly it is now tagged onto a SYD so it makes it difficult for crew to take someone along...
Hope this helps.
