Please can the Lurkers clarify this: is the 3000 points bonus for staying at three different brands a one-off or is it awarded for each group of three brands stayed at during the promo period?

There is some ambiguity between the wording in the heading you just posted and the T&Cs.

Which is correct? How many points will be awarded if a member stays at (Four Points + Courtyard + Aloft) and then (Marriott + Sheraton + Westin)? 3000 points or 6000 points?

Thanks for clarifying.
