In the very old days, when I was an Oceania cruiser, Oceania permitted me to get an on board credit for future cruises already booked with my TA once on I was on board. I am sailing on Regent for first time in November but I have many future Regent cruises booked. Will I be able to get an on board booking credit applied to those future cruises? Not all cruise lines do it (Silversea is one example).
