We just did this for our Carnival Cruise. We did a pre night at BWVs and had gardengrocer send 2 cases of water and a 24 pack of diet coke.
It, too, had to be carried in our carryon, which worked fine, although a little heavy.
We will be driving next year for our Dream cruise and will also want to bring on soda, water and beer. Can you please let me know does the beer have to be in plastic bottles or can it be carried on in glass bottles?
Thank you all.
