Here is the wording. I tried NCL and they won't discuss it with me since I booked through a travel agent.
We paid $5600 for the cruise which at the time was the amount on the NCL site. I have reached out to our TA again. This morning she said she couldn't help, I had to call NCL. Hopefully she will try and help.
Thank you for contacting Norwegian Cruise Line. We have reviewed your request and unfortunately, the shareholder benefit excludes Reduced Rate programs (e.g. employee rates, interline, flexnet, friends /family rates, vendor rates, cruises taken via cruise credit certificate, or free cruises earned through Oceania Cruises loyalty benefits). Therefore, we are unable to apply the onboard credit to this reservation. You can review the terms & conditions at the bottom of the following page:
