What happens when I stay at a Starwood hotel on a StarPRO rate and pay with an SPG American Express card?
Will I receive:

a. 5 Starpoints/$ (1 base, 2 from SPG, 2 from AmEx)
b. 3 Starpoints/$ (1 base, 0 from SPG, 2 from Amex)
c. 1 Starpoint/$ (1 base only)

I know the Amex T&Cs talk about "eligible spend", but are they really tied that well into the SPG system that they can tell whether a charge was for an ineligible stay?
Trying to decide whether to pay with my Sapphire or SPG card. Thanks!
