Thanks so much for your mini report on your stay! It was not clear to me what (little things) you felt were missing, particularly in comparison to Amanbagh. Maybe you can clarify if you have a moment.
In hindsight I miss Amanpulo more than any other Aman. I think it is because of the beach and water, primarily - which was astounding, rather than the hard or soft product itself per se (which was also fabulous). Being in a beach casita was perfect for me, but the tree top casita with pool also sounds very attractive.
