Registration is now open for Club Carlson's summer promotion. Between May 13 and July 21, 2013, you'll earn 10,000 bonus Club Carlson Gold Points for each paid stay of 2 or more nights at Club Carlson properties. Unfortunately Cash + Points stays are not eligible for the bonus.
You need to register for the promotion before you check out during your first eligible stay, which you can do here.
Update to the website: current hotel promotions all in one place
As you can see, in the top right navigation bar I've now added a simple page listing all the current hotel promotions that I'm aware of and registration links for each one. This is a handy way to keep track of all quarterly and seasonal hotel promotions, which typically have different start and end dates, and to make sure you're registered for all of them, which is free and easy. Check it out, and be sure to let me know if I'm missing a promotion or if there are other hotel chains you'd like me to keep track of.
Obviously I'll continue to post to the blog when registration opens for seasonal promotions, reminding you to register now, before you forget!
