The best spa treatment and facility I have experienced so far is at the Peninsula Hongkong. The package I availed was a full day detox treatment. I have this penchant for detox packages since obviously I know I have much toxins in my system.
I actually won this treat during the 2nd Spa Crystal awards held at Hua Hin but when I was trying to book last Oct 2006 the place was full. Fortunately I had another chance to visit Honkong early this year.
