My fiancé and I recently stayed at Amangani as the site of two friends' wedding, and we thoroughly enjoyed the experience. From the airport pick-up to the wedding coordination, everything was amazingly professional and well-managed. The location is, of course, breathtaking, and the facilities are tastefully decorated and totally relaxing.
The staff are all top-notch, and the service is really the best that I have experienced: extremely helpful and friendly, but also discreet and super-efficient. I was particularly impressed by the wedding and events coordinator and staff. Lena was a joy to work with; she handled everything with warmth and utter professionalism. I got the impression that the Amangani staff enjoyed being part of the wedding ceremony, rather than it simply being part of their job.
This was, hands-down, the nicest place I've ever stayed, and I look forward to our next visit!
