Also, as we found out on our last cruise, if you have excursions booked on CC, they will add those in the first day, even if CC is the last day. While we planned to put gift cards on our account before anything was charged to our credit card, the first day we were already over $500.00 and had a charge. They reversed it for us and took the gift cards, so it worked out, but just be warned. And in the end the excursions were cancelled so we got credited for those anyway.
