Hope this helps you out.
I take like two bottles of water with me then keep refilling them with
their water on the ship. At the fountains the water is good to drink.
Pop I think is one case. Wine is one bottle per person I think.
all your questions can be answered there..
If you take water or wine on board, pack it in your suitcase. Someone in our group brought a cooler of water and they confiscated it before we boarded and we never got it back after we got home. I packed some water in my suitcase and did fine, just don't bring it on your person.
