Find Your Cruise
Reservations@pocruises.com is an email address you could try. If you go on the web and use My Account there is another option within that format to email them. In any email by whichever option always quote your P&O reference as well as your name and postal address.
Although I know some personnel at P&O I, and others I would hope, would not give out this information on an open site like this. Your best approach is to ring them on 023 8065 5000 and ask for customer services. .... Neil.
