The review below is the personal opinion of David Poussif and not that of SafariBookings.
Don't book!
The experience with this tour company was bad since the beginning. The communication by email didn't flow, and I always had to chase up Charles to get more information.
They offered me a good price for a 4 days camping safari, I accepted and rejected another tour operator (7wonderssafaris) that gave me a cheaper quote, because Charles seemed to have better reviews.
Charles asked me for a deposit a week earlier and the whole payment in cash the day before the safari, which I didn't feel comfortable to give because even the day before I had to chase up after him to communicate and he still didn't know who the guide will be or what time they would pick us up the next day.
Apparently Charles had another bigger group he would be guiding. This is understandable, but the guide we went with wasn't good. The other tourists complained that he didn't communicate anything with them. I was always talking to the guide and then passing the information to the rest of the tourists.
Even worst, to my surprise, it turned out that this guide was actually from 7WondersSafari !!!
So at the end I paid more to go with the company I rejected because they didn't have good reviews.
The safari itself was good, but the communication and service was deplorable. You can check what we saw here: https://ubuntutravelblog.wordpress.com/2016/10/07/safari-in-tanzania/
