First time on NCL so questions may sound noob. If I board and go to a bar and ask for Macallan and let's say the bartender say yes then could I not right there upgrade the package or even worse case scenario go to assistance desk and upgrade ? Or if they say no then make a determination on what alternatives they have ? Its fair to assume that what we find on the ship may vary but once you are on the ship then the uncertainty is reduced, no ?
or are you saying that those package upgrade can only be done prior to boarding. thanks
