Take whatever you want aboard...be prepared to be refused IF it is discovered and the cruise line wants to enforce their policy. I've carried NA beer and diet cokes onboard b/4 with No trouble. I've heard other folks stuff was held till EOC. Its a crap shoot.....probably be OK.. IMHO....A MORE troubling concern????? If you mated a bulldog and a shitsu, would it be called a bulls++t? Happy kruzin'
