Spring break is coming up and one way to save money is to earn a free night at your hotel. The Choice Hotels spring promo lets you do just that. The cool thing about the promotion is that once you earn your free night you can choose to stay at 1,500 hotels across the globe – gratis! Here’s how it works.

Stay two different times at any of the ten hotels in the Choice Hotels chain, including the Quality Inn, Cambria Suites, Comfort Inn, Comfort Suites, Quality, Sleep Inn, Clarion, MainStay Suites, Suburban Extended Stay Hotel, Econo Lodge, and Rodeway Inn. You can mix and match which hotels you stay at. Each visit has to be at least two nights.

Stay twice between now and April 30, 2010, and you earn a free night. You can find a great hotel rate on the Choice Hotels website, which searches the entire hotel chain for the best deal. Within any given city, you can search for hotels by radius or by proximity to prominent attractions, like SeaWorld in San Diego or Walt Disney World in Orlando.

Make sure to sign up for the Choice Hotels privileges reward program to get your free hotel night. You’ll need an address in the U.S., Canada, Mexico or eligible countries in Latin America, the Caribbean and Europe to qualify for the promotion.
