Can we bring our own drinks and wine

You can bring bottle water, soft drinks, and a bottle of wine but it is all dependent on a limit per person..

750 ml for a bottle of wine in your carry on bag for the cruise 12 cans of sodas I believe no water allowed

Yes .with the wine only one bottle per person but it has to be packed in your luggage that's being handled on to the plain " not your Carrie on , they'll take it. On soda I think one twelve pack per person you can Carrey on call Carnival to find out for sure on sodas..

You have to hide it
