Club Carlson, the brand behind Radisson Blu, Radisson, Park Plaza and other hotel chains, is offering a 50% bonus on purchased points through November 10, 2012. Each member can purchase up to 40,000 points annually (60,000 with this bonus) and the rate is $7/1,000 ($7/1,500 with bonus).
With cash+points redemptions starting at 5,000 points and straight room redemptions starting at 9,000 points there are definitely some value redemptions to be found with this deal. That said, don’t think that you’re going to necessarily be getting a room in a Radisson Blu at a great rate, even with the discount. The relatively low max purchase amount and the high redemption rates for the nicer brands (many are 38,000 or more points/night) means that this promo is probably better suited to lower category redemptions than not. Still, take a look at their hotel categories and see if a property works for you. Might be worth buying up a few.
