Often times when a property can no longer uphold the Comfort Inn standards, it will downgrade to the Quality Inn flag. For instance, the many exterior corridor Comfort Inns that have disappeared in the past 7 years, many are now branded Quality Inn.

It used to be, 20 years ago, in the US at least, Clarion was the top Choice offering, Quality was the 2nd quality Choice offering and many properties were full service 3 star type properties, and Comfort was the 3rd quality Choice offering with more limited service properties and exterior corridors.

I feel like the only brand with any real standards at this point is Comfort. Clarion has gotten to be horrible, way too many old 70's Holiday Inns. Quality is also horrible, way too many old 70's exterior corridor motels. Comfort tends to be pretty good with many purpose built but also we see some recycled properties getting that flag too. Sleep I have limited experience with but they seem to be more purpose built.
