I booked Hawaii cruise a year ago for September this year with Book Later certificate. Unfortunately due to my work schedule change I had to cancel it yesterday. So, when I called to cancel, the agent said that NRD changed to $900🤯 we didn't do any changes to reservation since it was originally booked. Had to escalate to Resolution department and argue that my invoice says $100 NRD per person. I was told that the rules are changed and I was responsible for the full $900 deposit. But they will make exception for me this time since I didn't know and will only withhold $200 and give refund for the rest of the payments. BTW the final payment for this sailing is June 24. Lesson learned, we have another cruise booked for October of 2025 with Book Later certificate, so I'm not planning to make any payments till we get close to the final payment date.
