RCCL finally credited me for the Freedom cruise and I am now a Platinum member. Priority check-in awaits!
I don't understand why it took so long. Some people on our June 4 cruise got upgraded within a couple weeks of the cruise ending. I e-mailed the C&A and they said it could take up to 3 months to get credit for the cruise. And they were right. On September 4 my RCCL account finally showed Platinum level.
