I always wonder what the room rate is for if not to pay for the room and related expenses, like making up the room. And having tipped positions in full service hotels seems even worse: the hotel expects you to pay a premium for excellent service, that has to be paid additionally through tips at each interaction :-(
I'm currently staying at a Courtyard (have so for three weeks and will stay another 3 weeks at least) and wouldn't dream of leaving a tip in the room. Moreover, I'd expect any money left lying in the room to be untouched when I come back in the evening.
The OP never stated in which country the Courtyard is located...
