I had an amazing trip to South Africa in August of 2013. My brother and I did a 7 day plains game rifle hunt. We stayed at Wild Wildebeest Lodge and the accommodations were top notch. Wild Wildebeest and Numzaan had a partnership where Numzaan had the professional hunters and connections to the hunting concessions. They have since split their partnership, but I'd go back and hunt with either of them. The guides were first class and the game was plentiful.
My best advice would be to tell your guide how you want to hunt. We spent tons of time chasing critters through the bush while another in our group spent lots of time sitting on water holes. By the end of the week, it was very relaxing sitting on a water hole and watching animals up close and I wish I would have spent a little more time on water holes. If there is something you want, ask and Numzaan or Wildwildebeest will deliver!
