As usual, I apologize in advance for my poor searching skills if this one has been asked and answered but I'm also interested in recent stacking success.

Is this possible for my upcoming stays at the GH Guangzhou:

My assumption is that it will work but will likely require a call to CS after the stay. 7k bonus points for each stay looks pretty good (not to mention the double stay credits). If GHGZ offered the 1000 Diamond amenity...
