Good point Dr.! I am guilty of checking a shrinked wrapped 12 pack of water in a sports bag recently. I did insulate it with our swimwear. I didn't lug it to the pier, the porter took it out of my trunk and tagged it for me. It arrived just fine.
However, I did not think about it bursting and destroying someone's clothes. I would not want to be responsible for that. I am going to lug it as a carry-on next time. As long as Carnival allows me to bring water I am going to.
I don't like the ship's water and it doesn't like me. I know we have had many discussions about how pure the water is. For some reason it does not agree with me, so I try to limit my consumption.
As far as having something brought to me on vacation, I totally agree. And my Sail & Sign Statement can attest to that.
