I noticed this message on the bottom of a booking I made last week at the Sheraton Warsaw. To me it clearly refers to airline program miles and points, not to SPG points which remain in one's SPG account. Since credits to the airline side of this program have always been treated differently than points to SPG itself [and I still don't understand the airline mile/point option], I would have expected to see a more explicit: "No SPG points are given for this stay" as is the case with bookings made using a combination of SPG points and money.
I guess we shall have to await Lurker's stand-in, or his own clarification, after Christmas.
