Here you go...
Early Saver price drops and Platinum question.
There's a link in the thread to the form you need to complete, and a little further down there is a link (that I posted) that allows you to confirm that the room you chose is indeed cheaper. To the best of my knowledge, you are only guaranteed refunds / ship credit when your booking price falls, IF you originally booked the "Early Saver" rate ONLY. All other promotions are NOT covered by the price protection guarantee, Unless you booked your cruise in the last 48 hours.
