The only way the math works on mine was for them to do 7 points per c.c and then add 3 bonus points since I started at 5 c.c's.
, but am not sure, that I started with five cruise credits also. My Platinum status was due to having attained the Select level in Celebrity's Captain's Club. I've had just two Royal Caribbean cruises -- 17 nights total. I still can't get into my account on Royal Caribbean's site, so I'll have to talk to a human at some point.
So, what does it mean to have 38 credits? Is that still Platinum, or is it likely I've been demoted? According to Celebrity's site, I am still Platinum, yet I don't know when it was last updated.
