Booking cruise on points after a cruise?

[iloveokw]

To get the discount do you book onboard or is there a time deadline to book after you disembark? Thanks.

You can not book on-board using points. You would need to call within 3 days of your cruise ending to be able to book on points and get the discount.

Does this only happen if the cruise you were on was booked for points?
