I had an excellent safari experience. Saw 4 of the big 5 on the Serengeti in one day which can be difficult because of leopards are very reclusive. Saw 3 of the big 5 at Ngorongoro Crater and Tarangire also in one day. Did not have the chance to visit Olduvai Gorge. The campsite for Lake Manyara was not up to the same criteria as at the Serengeti or Ngorongoro as it was located in town. I had private tour at Lake Manyara and Tarangire as I was the only one to sign up. There was some confusion as to which operator that I would be with because the operator is based in Kenya and hires local operators for Tanzania but everything worked out. Our guide was able to point out animals to far to see which allowed the group to see a couple of rhinos and a male and female lion.
Tour operator .. amazing! We loved this trip. What a variety of game parks and sites to see. Pre and post tour attention was incredible. Only thing was, maybe an option to request camp beds instead of mattresses for us oldies! Thank you for an amazing experience. Well worthwhile.
