The review below is the personal opinion of Jerry and not that of SafariBookings.
Avoid this company at all costs
I recently did a 4-day Safari with World Tours and Safari in the Serengeti and Ngorogoro Crater. It was a once in a lifetime experience that this company continually tried to sabotage. I booked three months in advance to go to Tarangire, Serengeti, and Ngorogoro. When I arrived in Arusha, the manager Richard changed my itinerary so I never made it to Tarangire. Then, he tried to cut my Safari short by one day so we could drive a separate party to the airport. When confronted after the trip with these complaints, Richard was rude to myself and my family. He never even addressed our concerns as we attempted to talk to him in a calm manner. I later found out he suspended the driver for our trip, who was by far the highlight of the trip and pleasure to be around.
If you are looking to book a safari, just avoid this company. There are plenty of great companies out there operating similar safaris that there is no need to deal with Richard and the hassle of World Tours and Safaris.
