Hey!!!! That's pretty ironic, usually he Carnival cruisers are self-cre dialysis patients, but it does require power and water. However, our JimC is on this cruise, so we should have a pretty good account of what it was like out there.
We just finished 48 hours without electricity and it was trying. Can't imagine the lack of water. We figured if need be we'd melt snow, at least for toilets and such. Course the shipboard systems don't work quite the same.
