Today I made 2 online bookings for a free 7-night stay for Jan 23-30th, 2009, so the 50 weeks are honored by this particular cat.6 hotel.

By the way, I would suggest to make your reward stays bookings during February before the points devaluation strikes again increasing the category of your desired hotel. Last year they were +500 hotels upgraded and I fear that we may see a new born cat. 8 pretty soon.
