I used the new Amex SPG Luxury credit card for a pre-paid room reservation at the St. Regis Bora Bora. It did not get categorized as 6x points, nor did I receive the credit (charge was greater than $300). When I called Amex to enquire, I was told this is not a participating property for 6x points (?). I have asked for further review and Amex said they will get back to me.
Anybody else has faced the same issue at the St. Regis Bora Bora or any other Marriott/SPG property?
