I am considering to take the wife for a long-weekend in Cape Town in mid-November, both flights overnight in business class. There's no time lag to speak of from the UK so I figure a short stay might work. I'd love to stay longer but she has much less holiday days than me.

For those of you who have been there, would a 4 night, 5 day stay be sufficient to do CPT and the immediate surrounds justice? Or is it simply not worth the trek and we should stay a week.
