I stayed in a new CY in CA and it was really nice. The rooms were great (we got upgrade to a suite as MR Gold) and the bed was comfortable. The location has a CY and a SHS and we picked the CY based on TA, and we were happy with our choice.
I do wonder about how CY can be competed with other business hotels in the US. Here in Europe there are Marriotts, the Ren and CY and 1 RI. So for budget traveller like us CY is our choice because it provides a good Marriott quality without paying for the FS. In the US there are so many others, and in a way SHS is kind of a direct competitor to CY.
