I just reserved the Crown Grille for our upcoming cruise. The screen showed dining credit, but I could not confirm without a cc#. I did not have my card on file, so I added my card, redid the reservation (4 people, each having a credit). Cost was $116, credit $116, BALANCE DUE $0. I too will keep an eye on my cc statement, but I think the credit was applied correctly. 🤞🏻
