Having just had a chat with the Manager at one of the Aman properties, it is as of yet unclear. Apparently there were some changes in the local building regulations which held up everything and may further delay things.

I was told there would be 100 rooms all with a private swimming pool! Oh, and they will sell 'memberships' (whatever that means) to locals.
It doesn't sound like an Aman, but there you have it.
