That's an exact quote from the 'updated' FAQ on Carnival's web site.
We don't drink any alcohol but we do drink quite a bit of soda & water and always carry it with us where ever we go as it's ridiculous to pay such outrageous prices for something that is 'dirt cheap'.
We will take our normal soda & water with us on our upcoming cruise in May. If it is taken from us, this will be our LAST cruise with Carnival.
The number crunchers are always looking for every possible way to squeeze every nickel they can, many times without due consideration to the long-term effect. If that's the way they want it, we'll take our vacation $ elsewhere.
