RCI did have them on the Voyager in 2002. The problem with them though is that they only allowed call brands. Any premium liquor wasn't covered. And only certain wines and beers were included. Hubby and I bought one the first day only to find out what we wanted to drink wasn't included in the card.
Luckily they were nice enough to allow us to return the card and refund us our money.
With that being said.....RCI does NOT have the alcohol cards any more.
