yup I had a JS suite on two different Oasis class ships and on one they were a bit snippy, and on the other after having eaten in one night, when I went back check menu and cancel. Well they seemed a little hurt and begged me to let them get anything I want from any restaurant. I just told them I wanted a nice salad from the buffet and they sighed and let me go. I felt bad just a bit.
CK is IMHO not meant for every night since there are so many other places to eat on the Big ships.
