Expiry: Jan 31, 2018
Best Western Rewards members can redeem 10,000 points (or less) for a FREE night. Redemption offer runs between November 1, 2017 and January 31, 2018. The discounted FREE night offer is valid for stays at Best Western branded hotels in North America. Registration not required.
I tested with a Best Western hotel at Banff in Jan. You can see the price per night is over $200, but you can get one night with 10000 points (it is usually 20,000 points per night for this hotel). Pretty good deals.
If you don't have enough points in your account, you can purchase up to 5,000 points as a one time courtesy during the promotional offer to use towards one free night reservation during the promotion period.
