We cancelled our April cruise at the end of February with Costco. You need to contact Costco, the Cruiselines will not help you. We got everything back except our deposit, this was before the change in the cancellation policy. I have been trying to reach Costco, been on hold for more than 15 hours over the past 5 days. They keep you on hold for 3 hrs 1minute then automatically disconnect you- very very frustrating. If you want to cancel, you can send your name and cruise info to Cruisecancel@Costcotravel.com- they say they will process cancellations starting with the earliest departure date.
