This is one of the best promos I've seen in any hotel chain for a long time. I typically have 7-9 nights stays, so it fits my stay pattern perfectly.
Particularly the 4x bonus is surreal, esp. when you think it yields 62 points when combined with Surpass: It means someone staying in a Category 3 hotel like DT Bangkok and spending $120/night will get 3 free nights for every 8 nights stay. A whopping %38 yield on money spent.
(120 X 8 X 62 = 59,520)
Still, I reserve my final judgment until I see the exclusions list, as I fear that such a kick-... promotion may get tons of properties opting out.
