I'm prime, so I have the certificate that gives a 7-night cruise, with only a few restrictions (no new ships, no holiday cruises, some blackout dates on some ships). But when I called to redeem it for a cruise I booked through next cruise, I was told I was not allowed to do that. Has anyone else had this issue? I've often booked through next cruise to secure the room and sailing, and then just applied the certificate. The service rep told me, the rules changed. But I've never seen a notice on that and there is no restriction on the certificate. Thanks!
