just as important the 1st person listed on the tickets is considered the person responsible for the room. so if something in the room is damaged or stolen, stuff is taken from the minibar/frig, calls are made on the phone, etc... its the responsibilty of #1. kind of a bad situation but i guess theres nothing else the cruise lines can do because somebody has to be responsible for the room. on a singles cruise my roomie missed the ship in one port and got back on in another port and a family member died too. my roomie made as few calls as possible but the bill was about $150 for about 6 or 8 calls on my account. always have extra cash or a credit card with some credit available. the cruiseline will not take checks and you won't be able to leave the terminal untill your bill has been paid and they don't care if you miss your flight.
