The Courtyard Waikiki says they're offering 5000 bonus points "every" night, using code M11 with a minimum stay of 3 consecutive nights before March 31st. The flexible calendar defaults to a 5 night stay, but I was able to use "edit" to change to a 3 night stay and still see the rate.
Maybe they mean per stay? bejacob has also mentioned how difficult it can be to get hotels to credit local bonus points. Waikiki is not my idea of a Hawaiian getaway. 15000 bonus points, plus possible Megabonus points on the otherhand, makes a $650 bill for three nights a lot more acceptable, if you're able to squeeze it into your plans. And nationwide, they're saying "no resort fee."
