I am interested but sitting on the fence. They would be for future use rather than now, as despite having 8 cruises with P&O/Princess booked, I can not claim the OBC. After a few emails with them, I can not use the shareholder benefit in conjunction with Friends & Family discounts (Note: not complaining).
But I will only receive that for as long as we have a friend who works at Carnival House.
Looked previously, but at the higher price was too much of a luxury. Now though @ 730p is a different proposition.
Now to go and find that crystal ball.
