You can check on the Carnival web site and see if you have any offers. You don't have to wait for the mail to arrive. Log onto their website, then click on "cruise deals" at the top of the page. Then click on "past guest offers" in the middle of the page. Then click on "VIFP Offers". Enter you VIFP number if it isn't already entered automatically. Then any offers will show. I currently have a "free interior cabin" and a "two category upgrade" offer available.
