Most cruise lines will auto upgrade when you book thru an interline agency that has a good standing, ie preferred status. I know with <a href="http://www.Interlinerates.com" target="_blank">http://www.Interlinerates.com</A> they will check for you and many times they will do a complimentary upgrade, if your documents have not already been printed.

The other option is to ask at the pier. I have found that last minute stuff just doesn't happen as much as it use to. If you don't ask, you don't get! As always, non rev rules apply, after all interline rates are a privilliage not a right.. Be nice and you never know what you might get.
