As a member of the Club Carlson Hotel Rewards program, you can EARN Club Carlson points. You can then USE these points to book free travel. Carlson Rezidor has many hotel brands with over 1,000 hotels. Carlson divides its hotels into ascending categories, in their case seven, with the more budget-friendly, full-service hotels in the lower categories and the more luxurious hotels in the upper categories. The Hotel Category determines the number of points required for a complimentary night.
