I have been to Amangani twice, both in winter for skiinng and summer for sightseeing. I would say that the best Amangani has to offer is the stunning view that makes you feel like living in the sky. The facility is pretty good but not on the scale of the asian aman. Service is americanized but still very decent, and it did improve on my second visit. Just keep in mind that Amangani is not set to be a destination hotel like other asian amans where you can literally stay in the hotel's ground during the whole stay. It is there for your comfort and convenience while you explore the magnificent grand teton and yellow stone national park. For me that is why I go to Amangani. So from this prospective, Amangani is more than sufficient.
