I just got the newsblast to be sure my SPG number is registered.
As far as I can see, the site doesn't hold the number anywhere, so though I remember doing it via the Booking/Starwood Promotional Offers drop down menu link, I can't see if it was saved or if I should do it one more time. (it says if you do it more than once, only the latest info will be used)
Should I be looking in a different place to ensure that I am registered already and you have my number?
