I am going on the Millenium in June of 24. I am thinking of getting the Zero Proof package but I typically only drink Diet Coke as far as soda goes. I was watching a video of someone who went on an Asian cruise, different cruise line, and they were served Coke Plus. I know Japan does not have Diet Coke and was thinking I could get by until I got on the ship but now I am wondering if they will even have it on board since they will be in Asia for a while and it is not available there. I do not want to commit to a beverage package I probably will not use enough if Diet Coke is not an option. Anyone been on a Japan cruise and if so do they serve Diet Coke?
