I received one of theses letters on my oceana cruise in October. If I remember correctly it had to be used with 6 months of issue. Luckily I was back on for Christmas. At the end of the Christmas cruise I was given another letter but the terms had changed. In order to get my “free play £250” I need to book a new cruise and use by October 2020. Interestingly it says any further information to contact P&o players club, I can’t seem to be able to find anything regarding this. It did have phone number which turned out to be just P&o booking telephone number and placed me in a queue I was too busy to waitin. I may give them a call at some point as I book most cruises well in advance, booked right up to April 2022 so can’t really book any more.
