I've never stayed at any Choice hotels, are they nice or are they roach motels?
They totally run the gamut. Many of the lower end like Comfort/Quality/Sleep Inn are sheer sheets and for the free breakfast slimy hard boiled egg places. Rodeway/Econolodge/Clarion I avoid.
Comfort Suites is like Holiday Inn Express. Clarion Collection in Scandinavia is fabulous with intricate buffets for both breakfast and dinner (free). Cambria Suites is good. Quality hotels in Scandinavia are also fabulous. Comfort Hotels is one of the most common French chains.
