I too have unsuccessfully attempted to book stays at this property. World20--what is there about it that makes it great? I'm a Diamond, and my company also has a 2300 Ffr rate-- If I ever decided to go for it, what can I expect as far as upgrades or service? On my recent trips to Paris, I have been staying (as a Platinum) at the Starwood hotels in Paris, and have been treated quite well. From the website it looks quite nice, but we all know that looks can be deceiving, and that some Paris hotel rooms have the tendency to be quite 'cozy'. I'd be interested to hear about others experiences here, since I will probably be back in Paris before the fall.
