Ok....this may be a silly question, but I just want to make sure...can you bring cash for the casino, or do you have to use your sail and sign card? A friend told me that you have to use the sail and sign card, and I was hoping to just use cash, so I can budget myself easier. We are sailing on the Carnival Fantasy if that makes any difference. Thanks in advance...these boards are so great! Thanks to everyone who takes the time to respond to us "newbies"!
