Maybe a question for the Singles and PWP section of the forum? I'm sure Carnival has dealt with two single cruisers booked in the same cabin but wanting seperate charges. If not, then maybe this would have to be settle on a case by case basis by going to the pursers desk? If they can establish a seperate charge account for each person's S&S card, then the only other room charges would be the towels and minibar usage. Anything else would be charged to that persones sign and sail card "folio" number (unless their system doesn't allow for two folio numbers to a cabin???
