I vaguely remember hearing about this benefit a few years ago.
Here is a recent link from TPG:

I was initially a little disappointed, because I recently redeemed an Amex Offer on my Platinum for $300 off $1000+ for Holland America.
However, it looks like the American Express Cruise Privileges Program is primarily geared to high-end luxury lines.
Holland America gets chocolate covered strawberries....
It also looks like the program requires double occupancy and I typically cruise alone.
Regardless, thanks for posting and Good Luck.
