We used Access2Tanzania for our trip and really liked working with Karen Stupic (firstname.lastname@example.org). She helped us plan places to go and make our travel arrangements. We camped for two nights outside Tarangire, stayed at Crater View Inn for a night, camped for three nights in Ngorongoro and Serengeti, and then stayed at the Mbalageti Lodge. We then went to Mwanza and flew to Rubondo Island for four nights. Our guide, Mohammed, was absolutely fabulous. He was one of the best parts of the whole trip. I would HIGHLY recommend asking for him. He has a great eye for spotting animals and knows a huge amount about wildlife. My wife and I had no prior interest in birds, but Mohammed made it interesting and got us excited about it. Our cook, Wilfred, was also fabulous. He cooked a huge amount of food when we were camping, and we never got sick. I would definitely recommend going with Access2Tanzania if you're looking for someone to help with a trip to anywhere in Tanzania.
