As noted in the Carnival FAQ you linked, you must have an 'WHTI compliant form of ID', and a RealID is not WHTI compliant, as the link clearly shows. Maybe I didn't word it clearly enough.īest bet is to dig up what Carnival says about it on their website.Īnd, those people using a 'star' (RealID) will either be carrying their birth certificates, or not getting on the cruise. No, I said I know several people who use their drivers license with the star ID (they happen to be from Michigan), I always carry my passport.
