Hello, my boyfriend and myself are looking to do a safari leaving Arusha or Moshi on April 26 to Lake Manyara, Serengeti and Ngorogoro for 3 nights, or just 2 nights with Lake Manyara and Ngorogoro. Our budget is around $100 - 150 per day (~$500 for 4 days). Looking for recommended companies and a group to join!
