Mara Siria is a nearly perfect safari experience. The accommodations are comfortable and open to the great views of the Mara. The tents are well separated from each other. All the amenities are there except piped water to the tents - so you have to give notice for a hot shower. (A triviality). The food is fine, or great considering the supply challenges. Service throughout is wonderful. In fact we wished they would back off a little at meals. Safari guides are really top notch. Ask for Paul. The 20 minute drive up the track from the plain to the escarpment edge to the camp is unbelievably rough. It was hard to take after a long day out in on the plain.
The following criticism effectively evaporates once one arrives at the camp; the website is spare on details. For instance the luxury tents are a lower value than the deluxe. But these terms are distinctions without difference in English. Since no prices are listed one does not know what you are buying. The reservation process with Safari Tours is frustrating because one can't get answers to specific questions, or commitments regarding a particular tent, or any other special request. They ask for all the money up front but provide very weak documentation.
