Hard to rate but here is my attempt - I think after the first 4 or 5 it gets really hard. Room stayed in also made a huge difference in my selection!

Amanjiwo - we had a magical time there - only two other couples were there and it was just spectacular - one of my most memorable Hotel experiences
Amankora - another fabulous experience
Amanpulo
Hotel Bora Bora - so sad it is gone
Amankila
Amandari
Amansara
Amanwana
Amantaka
Amanpuri
Amantaka
Aman - I - Kas
Aman Tokyo
Amanusa - I guess its now only villas
Amanjena
Amangalle
Aman Sveti Stefan
Amanwella
Amanruya
Aman Le Melezin - quite a long time ago so I assume it has improved a lot!

I guess given I live in California I have to make it to some of the US properties. I have had dinner at Amangani in Jackson Hole but never stayed as always with friends in home for skiing! Also hope to visit Amanoi in the not too distant future.
