I am arriving in Cape Town on the 19th, leaving on the 24th, so have 4 1/2 days to myself there. I have on my list Table Mountain, a day tour to the Cape area, Constantia, Kirstenbosch Gardens and the inner city things like museums, galleries and the Company Gardens. I am staying in the Gardens area. Should Robben Island be included, or is it not really worth it (in spite of its history) given my time factor? I've had Mortons at V&A and Bukhara recommended for good food.
