Club Carlson used to be one of my favorite hotel loyalty programs. On the earning side, they used to run some killer promotions that were totally mattress runnable. The best of those awarded 50,000 Carlson points for one a night stay at a Radisson hotel, basically enough points for a night anywhere in the world.
On the burning side, you could get a free award night on every redemption, so long as you had the Club Carlson credit card. This amounted to BOGO award nights and effectively doubled the value of your points.
Those days are long gone, however. And Club Carlson recently devalued their loyalty program even further by taking away a somewhat obscure but valuable benefit for Carlson Gold and Concierge members.
