The list that Club Carlson initially had with the new award promotion was incorrect. They have now updated the list and the number of participating properties is a LOT shorter.
There are no hotels that would be on sale for 4500 Club Carlson points contradictory what the text above is saying. The discount code 50REDEEM is now working and deducts the 50% off of the number of points required for a free night.
Only the following properties are participating:
Belgium
Croatia
France
Georgia
Germany
Ukraine
Radisson Resort & Spa, Alushta
Conclusion
The new list is really disappointing. They had forgotten to update the list of participating properties, when they launched this redemption promotion.
