To get started here is my list:
City Hotels:
1) The Shangri-La, Kota Kinabalu
2) The Ritz, Hong Kong
3) The Shangri-La, Singapore
4) The Grand Hyatt, Kuala Lumpur
5) The Shangri-La, Kuala Lumpur
6) The Lanesborough, London
7) Citidines, Bali
8) Banyan Tree, Bangkok
9) Mandarin Oriental, Bangkok
10) Raffles Hotel, Singapore

All these names of hotels being listed are all biased towards western hotels for guests who only travel to those destinations and do not reflect the reality that the very best hotels in the world are actually outside of the USA and Europe. I know many will disagree with my list but that's how I see things.
