On our last cruise we ordered subs from room service to take with us on our excursion. Used the ole zip lock bag to keep it in that way we did not have to buy lunch or go back to the ship for it.I think that in a lot of ports, you are not supposed to take food off of the ship. Check with your specific cruise ship before you do this.
