Terms & Conditions on mine said book a cruise within 6 months to gain OBC, if this has not been done then you have another 6 months to book (but you receive no OBC), nothing booked within timeframe or if the timeframe expires (1 year) then the deposit you put down was non-refundable.
The above is why I didn’t take up the offer, as it couldn’t be guaranteed that any future cruise I wanted to book (once I got home) was not an ‘exciting deal’ which it cannot be used with.
The future cruise team told me to call the UK sales team from our cabin so I did, they told me that I needed to speak to the future cruise team on-board, I was just going round in circles!
The very small print at the bottom of the flyer that they keep placing in your cabin does say not combinable with ‘exciting deals’ but you won’t know what cruises are exciting deals until you go to book and then you will be told that you can’t receive the OBC!
