I hope it's worth it, we're using points for the same category. We've been on a 3 night
DCL cruise, and I think the stay at CC is a wonderful experience not to be missed. If I had it to do over again, however, I would have just booked an inside cabin for fewer points. We didn't know if we would like the Cat. 10, we cruised DCL after we booked the MC.
Best wishes as you make your decision!
