I am not sure why it isn't advertised yet, but they are running a 'special' this fall, and reducing points. I had booked a Cat. 10 in Sept on a 3 day cruise for 78 points per adult, and it was reduced to 70 points each and they added a $50 on board credit!
They called me last week to tell me the good news, and I got a letter today with confirmation information.
So if you want to cruise this fall (don't know if it is just for September or not), you could probably do it for less points than is listed.
