I'm going on a week long cruise. It is NCL. And I'm wondering how to get it onto the plane firstly. Do I just put it on my luggage? Is that allowed? And if I do get it past the flight what is the best way of getting this ontothe cruise??

Also I am NOT 21. So That may complicate things idk...I'll be old enough to "legally" drink on and off the ship since that is only 18 to drink. Im expecting some answers telling me I'm stupid for drinking when I'm "underage."
