Several hotel, airline and credit card loyalty programs allow members to redeem points or miles for free hotel stays. Online booking agents such as Priceline.com and Hotels.com may post different offers for a free night's stay.
Redemption rules vary by company and hotel location, making it necessary to check the terms of individual loyalty programs. For example, the Hilton and Hyatt hotel programs let travelers book free rooms from as little as 5,000 points, whereas Marriott's free nights start at 7,500 points, as of June 2015.
Hotels.com offers its own rewards program, independent of hotel chains, that gives users a free stay after 10 hotel bookings made on its website. Priceline.com regularly updates a list of free-night deals offered by specific hotel locations.
