First bonuses posted:
1. As advertised, you get a total of 8000 points for the two stays, no matter what you paid for the stays.
2. Any elite bonus (e.g., the 40% Diamond bonus) is in addition to 8000 points.
Point 1 seems to really encourage hotel-hopping. The more nights you spend on any given stay, the less the bonus is worth.
OTOH, they ran two of these promos last year, and I thought they were gooder than sex. I really racked up a pile, only to be eclipsed by the recent 3/16K promo. So, I'm gonna work this one, too. After all, the odd 100K points here and there is bound to come in handy for something, right?
