For me, at the time of our first cruise, putting the soda in the carry on was not an option. I was a single mother, traveling with my small children. My small carry on had to hold all the things that my whole family would need that day, medications etc., in case our luggage was late getting to our room. And, I had to keep it light enough to manage it and the kids, knowing that there was a possibility that I may not get to put it in the room until after 1:00. There was no way I could have included 24 Mt. Dews in that carry on bag. There was nothing in the mailed box that I would have died without. If it had not been delivered to my room, I would have been disappointed but I would have survived. It was definitely worth a try for me. In fact, I have done it for all my cruises and I will continue to do it. I know that the moral police on here will have a stroke over it, but it's not like I smuggled a gun or drugs on board.
