Attrition is the number of rooms in your contracted room block for which you will not be penalized if unfulfilled. We allow for a ten percent (10%) decrease in the number of rooms contracted without financial penalty, up to a cut-off date (30 days prior to the check-in date).For example, if you contract twenty (20) rooms, you are financially responsible for filling (“picking up”) a minimum of 18 room nights. The good news is that we count all of your group reservations toward your pick-up; therefore, if anyone in your room block comes early or stays late, those room nights will count towards attrition!
