I was in a terrible dilemma! The safari tour I was going to book had been canceled; I'd already booked my flights and had a limited time in Kenya/Tanzania. What to do! All the "big name" tour companies were either too expensive or their departure dates and length of their tours didn't fit into my time frame. When I discovered TourRadar, I was saved! There were a whole lot more tour operators (including the "big names") that I couldn't find on my own. Problem solved! I found a safari that fitted my budget and duration. TourRadar claims that they have vetted the operators that they have on their website. I can also pay in A$, so there are no problems with currency exchange fees on my credit card. My tour is a couple of months away, so stay tuned on the standard of the tour and the operator.
