If a hotel credit card earns points, you’ve got the potential to earn free nights. Once you’ve accrued a certain amount of points (dependent on the quality of the hotel), you’ll be able to stay there for free. Plus, certain hotel credit cards also come with one free night annually, meaning each time you renew your card, you’ll get a certificate for a free night — often worth between 35,000 and 120,000 points. That’s a big deal!
