Club Carlson has commenced its first 2015 promotion, called “Extend Your Stay, Earn 30K”. It offers 15,000 bonus Gold Club Carlson points for 2-night stays, and 30,000 bonus Gold Points for stays of 3+ nights.
You need to register for the promotion here, and stay between 12 January and 29 March, 2015 to qualify for the bonus points. Interestingly, there is no limit on the number of times you can earn this bonus during the promotional period.
Also, check your email! Certain Club Carlson members have been emailed to say they will earn an additional bonus of 10,000 points for their first stay of 2 or more nights.
Redemptions at Club Carlson hotels start at just 9,000 points for a Category 1 hotel, so this bonus will get you three free nights plus change. At the (slightly) higher end, the 30,000 bonus points will get you a night at a Category 3 hotel (with 2000 points to spare). The full list of hotels and points redemption requirements is available here.
