I just received an email from my Raddisson Goldpoints program - they officially changed their name now to Club Carlson. With the email, I received a nice 5000pts bonus for newsletter sign-up. Since free nights start at 9000 points, this bonus is significant.
Raddisson email excerpt: "Subscribe to our emails to be the first to know about hotel discounts, special offers and more. Subscribe today and stay subscribed until August 31, 2011 to earn 5,000 bonus points."
