I believe that all of the info is in the barcode at the top of the boarding pass. Your Platinum "Sign and Sail" cards will be in your mailbox outside of your cabin when you get there. Any official will see your status as they scan your Boarding Pass until you get your cards. Should not be a problem but, if so, go to Guest Services and they will straighten it out. If you have your 75+ days in the system, they will have that info.
