Friendly, reliable and responsive.
The tour organiser was extremely responsive and accomodating, as she made her best to answer our numerous questions and offer a tour that would be the most suitable for our needs (travelling alone with my 5-year old child).
The driver-guide was friendly and reliable, although not very talkative (which I personally prefer to a guide who is too chatty). His English was good and he was rather knowledgeable about wildlife, regularly checking information in books to offer us the most accurate knowledge.
The accomodation was on the overall good value for money and the minibus was quite comfortable, it just didn't have a very sophisticated air conditioning system, which meant we had to keep windows open (and thus let the sand in etc..) if we didn't want to suffocate from the heat.
The tour was quite a budget for us, but it was worth the financial effort because the opportunity to see so many wild animals is such a unique treasure which we will probably still remember in many years to come.
