I am sorry but my original post seems to have been misunderstood by several people. I am not concerned that the bottle will break.... I said that I will be traveling with some people who have difficulty with their carry-on luggage due to the weight of the luggage....without any bottle. They would like to be able to bring a bottle of wine on board, which is allowed on Princess, in their carry-on, but the bottle adds excess weight, along with the wine. If they could bring the wine in a plastic container, the weight would not be as much. All of this is mute because one of the first responders mentioned that the wine has to be sealed in the original container. Thank you all for your responses, even those of you who found it necessary to be nasty in your response, but I think this has been answered.
