European members of Choice Privileges who complete two stays at participating Choice hotels can earn up to 12,000 bonus points.
Guests must complete two separate qualifying stays between February 19 and April 22. The bonus points are not in addition to the amount normally earned during the two stays.
Twelve thousand bonus points are enough to redeem for a free night at over 100 participating Clarion, Clarion Collection, Quality and Comfort brand hotels in Europe.
Qualifying stays must be booked online at choicehotelsuk.co.uk or by calling 0800 44 44 44.
Brian Garvan, Choice Hotels Europe's director of European corporate sales, said: "With the busy March business period upon us we hope many business travellers will become Choice Privileges members and take the opportunity to earn a free night's stay at a participating Choice brand hotel."
It is free to become a Choice Privileges member. Signing up can be done either online at choicehotelsuk.co.uk or when checking into a Choice-brand hotel.
Members also benefit from express check-in and extended check-out times and can redeem points for stays at over 6,000 hotels worldwide. Points can also be exchanged with airline or other reward partners.
