Let me shed a little light on this subject.
The options relate more to what is happening in Cape Town and Birkenhead House and NOT to the game parks at all. Different arrangments, longer in Cape Town, Birkenhead House different dates all make the difference on the options.
All people just doing one night Cape Town in conjunction with Birkenhead House are option 3 BUT they can all be at different game camps. So Option 3 could be Mateya and Lions Sands OR Madikwe Hills and Leopard Hills or Madikwe Hills and Kings Camp.
Everyone is going to spend 6 nights on safari in two different camps. So dont worry too much it will all work I promise.
