I have been trying to extend a stay at the JW in Cancun for two extra days in February. I cannot get a platinum override due to some convention, and I have called the hotel directly several times as well as MR Customer Service. The neighboring Casa Magna is also unavailable.

They keep telling me that the hotel is already oversold. Well, isn't that what the platinum guarantee is supposed to be used for... getting a room in a sold out hotel!
