It seems as if there is an obvious defference between CY in Europe and the U.S. I have been to a couple of CYs in Europe (mostly ZRH and DUS) and they all were very modern, rooms were as comfortable as in "normal" properties (big flat screen t.v.), breakfast was better than in many more expensive hotels and prices are nearly as high as for a classic Hilton, Marriott or Sheraton.
But I have made the same experience with Four Points: In Europe they are mostly very modern, exclusive and expensive whereas in the U.S. I would never stay at a Four Points again.
I think the branding in Europe is completely different: Four Points and Courtyards are often not in downtown, have no first class restaurant but rooms and amentities are nearly the same as in a classic Marriott or Sheraton.
Just my two cents
