Not 1 free nite per paid nite. That would be nice.

You geht 1 free nite, if there is at least(!) one paid nite. If you stay 5 nites, you pay 4. The 1 free nite is once per year. But I donot know if once per Hotel or once in the whole chain!?
By the way: You can reserve with the german Amex Reservation System and see the Mandarin Oriental rates online.
Total cost is 460 Euros compared to 1300 Euros.
