Another response to this question and it was confirmed by others that P&O are going down the same route as Celebrity and Royal Caribbean and you will get a refund on your seapass account. So you will have the credit in your account when you join the ship. The problem of refunding has raised problems within the industry and it was thought the credit option is the best way forward.
Thank you for your quick response to my question. As I am going on P & O and Ocean Village 11 in the next few months, I wanted to know that they are offering a refund like other cruise ships. I will make sure that I check this out when I arrive on board on both occasions.
