Actually, it's possible that it could really be gba's Summer Promo.

My Summer Promo is 15 nights / 20k bonus.

I also have that two-stay-one-free-night thing in there, but I think that's different. Marriott fixed that issue, so gba wouldn't have seen it new today.

In My Promotions, Marriott really does call this one the "Summer 2009 Promotion". They don't use the term "Megabonus" like they typically do. Perhaps somebody figured out that 20,000 bonus points isn't really mega-anything. On 15 nights, it's a nice little bonus. But nothing insanely lucrative.

I don't make it...we're traveling Europe this summer and hitting boutiques and B&B's. Maybe if somebody else posts a lower promo, I'll call Marriott and ask to be downgraded to that. (They will typically do that for Plats.)
