While I was on the 8 day accommodated self-drive safari, I consistently had to ask myself whether this company was simply disorganized or was actually a scam. After the trip and subsequent communications with the company, I am convinced it's a scam. For reference, this is the same company as Enrico's Tours but changed their name due to bad reviews. A link to those reviews is at the bottom of this review.
1) My assumption was that they had made all bookings in advance when I paid my fees. This was not the case. They told me they had gotten the start date wrong despite me getting a confirmation of the itinerary with the correct dates, but my suspicion is that this was to cover up the fact they hadn't made any bookings. Instead of making all the bookings on the day this error was found, the location for accommodation changed nearly every day. In only one case had a booking been made and payment completed before our arrival out of 7 overnight stays.
2) The places where we actually ended up staying were consistently changed to a hotel or lodge at a lower price point than what was advertised on the itinerary we used for booking.
3) Twice we ended up having to pay for the stay ourselves (conveniently the 3 most expensive nights of the trip) and the company still hasn't reimbursed us despite repeated requests over the last month. The stress of never knowing if a booking had been made was a detraction from our trip. If we hadn't paid already, we would have set everything up on our own, but we were trying to get him to pay for accommodations whenever it was possible.
4) Most recently when I reached out about reimbursement for money we had to pay ourselves, his response was "Hopefully for my refund but Sossuvlei I am not sure but let me find out all I am back on Thursday and will give you indication exactly when. Because I am also waiting on my 5 star review." I think this indicates he would only refund us the ~$500 if we wrote a glowing review. I am not willing to deceive future travelers in order to allow this to continue.
I have filed a complaint with the Namibia Tourism Board about Enrico's Tours and Safari World Tours, since they changed their name but are still the same operation. Enrico's Tours changed their name due to all the negative trip advisor reviews (see https://www.tripadvisor.com/Attraction_Review-g293821-d13941947-Reviews-Enrico_s_Tours_and_Safaris-Windhoek_Khomas_Region.html).
All this said, you should absolutely go to Namibia because it's an incredible and magical place. But absolutely DO NOT book through Enrico's Tours or Safari World Tours.
