I feel like I have come across a similar thread, but cannot find it. We are three women staying in the same cabin. As I am the main contact for the reservation, I am assuming my credit card will be the one that will be charged at the end of the cruise. Is there a way that my friends can use their cards; meaning can we go to guest services and they use their credit card to credit my account or something like that...not sure if i am saying it right. or should we just wait till i get an itemized bill? I am just looking for the easiest way to keep track of charges. We are staying concierge which is our "guest services", right? anyone deal with similar situation?
